垫子看着软，用起来却打滑。硬度不是越软越好，防滑系数得先定。
软了还打滑，是没先定防滑系数
TPE 硬度调整，硬度和防滑一起看：硬度、摩擦、手感。结论先给：摩擦系数0.3和0.6，防滑两回事——防滑，是硬度的搭档。
TPE硬度调整最大的坑：摩擦系数从0.3跳到0.6，手感和防滑就两重天——摩擦系数，是防滑的尺子。
TPE 手感是品质关：偏硬、偏软都是问题。硬度对了，手感才稳——品质关，别省调试。
硬度是手感的尺子，为什么先定目标
TPE 硬度按件定：牙胶软，工具柄硬。硬度不对，手感差——硬度，是手感的尺子。
硬度调法：加填充变硬，加油变软。配方调硬度——配方，是硬度的开关。
硬度与防滑相关：硬度低防滑好。防滑测试写进验收——防滑，是硬度的搭档。
系数、测试、场景，怎么对
摩擦系数：0.3 和 0.6，防滑两回事。系数按场景定——系数，是防滑的尺子。
防滑测试：按标准测动摩擦。测试写进验收——测试，是防滑的考场。
防滑场景：湿滑、油滑不一样。场景不同，系数不同——场景，是防滑的目标。
硬度与防滑，一张表对照清楚
| 硬度 | 防滑 | 用途 |
|---|
| 软胶 | 好 | 防滑垫 |
| 中胶 | 中 | 握把 |
| 硬胶 | 差 | 结构件 |
| 超软 | 优 | 密封 |
表格读法：硬度越低防滑越好，用途跟着走，摩擦系数单独看一栏。
按场景选，防滑才对。
握着稳不打滑，验收测这四项
| 项目 | 要求 | 判断 |
|---|
| 硬度 | 按件 | 达标 |
| 系数 | 按场景 | 达标 |
| 手感 | 盲测 | 达标 |
| 批次 | 锁定 | 达标 |
表格读法：调整一项项核，手感看得见，0.3和0.6别混着用。
防滑，是硬度的搭档。
只盯硬度不看防滑，手感全错
坑一：只看硬度。硬度调对了摩擦系数没管，湿手照样打滑——防滑必测。
坑二：系数乱定。防滑差——系数按场景定。
坑三：手感不验。偏硬偏软——盲测必做。
硬度、摩擦、场景——调硬前问清
三问：什么硬度、什么场景、什么系数。一验：实际使用实测——三问一验，供应商底细清楚。
防滑验证要先行：先定使用场景是干是湿，再谈硬度档位——防滑，是硬度的搭档。
留样要成习惯：每批留样，硬度按批次复测。批次换料先对比再放量——批次稳，客诉少。
打滑、发粘、磨手：故障对照一张表
| 现象 | 原因 | 对策 |
|---|
| 偏硬 | 填充多 | 加油 |
| 偏软 | 油多 | 加填充 |
| 防滑差 | 系数低 | 调配方 |
| 手感飘 | 批次漂 | 锁窗口 |
| 回弹差 | 硬度高 | 调配方 |
摩擦系数0.3和0.6摸起来都“不滑”，湿手一握两回事。 防滑要按实际工况测，别只看硬度表盘，表盘看不出湿手差。
硬度是手感的尺子，但不是全部刻度。 同是Shore A 70，SEBS软糯、TPU弹韧，尺子一样、手感不同，别只按硬度下单。
防滑垫用超软胶、握把用中胶、结构件用硬胶。 按用途定硬度档，别一刀切一个料打天下，软硬配错件就废。
手感要靠盲测验收。 同硬度三块样摸完再打分，别让“软就是好”的标签带着走，盲评分不出软硬差才算过。
摩擦系数按场景卡到目标值、批次硬度收进±3A，防滑件用手不滑、放桌不跑。 盲测20人评分一致才放行，批次漂就是客诉。
硬度调档靠充油和填充，不是换牌号。每加5份环烷油Shore A降5-8度，加碳酸钙每20份升10度以上，手感从软糯变粗糙，填充加多了表面发雾。
同是Shore A 70，SEBS基软糯、TPU基弹韧、TPV近橡胶。硬度计测6mm叠片才准，薄件2mm读数偏软5度以上，验收厚度不够要叠片复测。
防滑按实际工况测，别只看硬度表盘。湿手摩擦系数≥0.6才算防滑，表盘看不出湿手差，盲测三块样摸完打分别让软就是好的标签带着走。
按用途定硬度档别一刀切一个料打天下，软硬配错件就废

总有人问：副牌料到底能不能用。
我们的回答一直没变——能用的地方很多，不能用的地方一处都不能碰。它和回料是两回事：一个是指标偏了，一个是分子链断了。
The mat looks soft, but it slips when used. Softer isn’t always better in terms of hardness; the anti-slip coefficient should be determined first.
It’s slippery when soft because the slip resistance factor wasn’t set first.
TPE hardness adjustment, hardness and anti-slip should be considered together: hardness, friction, and hand feel. Conclusion first: friction coefficients 0.3 and 0.6 are two different things from anti-slip—anti-slip is the partner of hardness.
The biggest pitfall in adjusting TPE hardness: the friction coefficient jumps from 0.3 to 0.6, and the feel and anti-slip performance are worlds apart——the friction coefficient is the measure of anti-slip.
TPE texture is a quality checkpoint: too hard or too soft are both problems. Only when the hardness is right does the texture feel stable—a quality checkpoint you shouldn’t skimp on during adjustment.
Hardness is the measure of how something feels in the hand, so why set a goal first?
TPE hardness is determined by the item: the teether is soft, the tool handle is hard. If the hardness is incorrect, the feel is poor — hardness is the measure of feel.
Hardness adjustment method: adding fillers makes it harder, adding oil makes it softer. Adjusting hardness with the formula—the formula is the switch for hardness.
Hardness is related to slip resistance: lower hardness provides better slip resistance. Slip resistance testing is included in acceptance - slip resistance is a companion to hardness.
Coefficients, tests, scenarios, how to match
Coefficient of friction: 0.3 and 0.6, anti-slip is another matter. The coefficient is determined by the scenario — the coefficient is the measure of slip resistance.
Anti-slip test: Measure dynamic friction according to the standard. The test is written into the acceptance — the test is the examination for anti-slip.
Anti-slip scenarios: wet and oily are different. Different scenarios have different coefficients — the scenario is the target of anti-slip.
Hardness and slip resistance, clearly compared in one table
| Hardness | Non-slip | Purpose |
|---|
| soft rubber | Good | Non-slip mat |
| China National Rubber | middle | Handle |
| hard glue | poor | Structural component |
| Super soft | excellent | Seal |
Table reading: The lower the hardness, the better the slip resistance. Follow the usage, and look at the coefficient of friction in a separate column.
Choose according to the scenario; that's how to prevent slipping.
Firm grip without slipping, inspect and test these four items
| Project | Requirement | Judgment |
|---|
| Hardness | By piece | Meet the standard |
| coefficient | By scenario | Meet the standard |
| hand feel | Blind test | Meet the standard |
| Batch | Lock | Meet the standard |
Table reading method: Adjust each item individually, you can feel it with your hands, do not mix 0.3 and 0.6.
Anti-slip is the companion of hardness.
Focusing only on hardness and ignoring slip resistance results in a completely wrong feel.
Pitfall 1: Only looking at hardness. Even if the hardness is adjusted properly, if the friction coefficient is ignored, your hands will still slip when wet — slip resistance must be tested.
Pitfall 2: Coefficients are set arbitrarily. Poor slip resistance — coefficients should be set according to the scenario.
Pitfall 3: Ignoring the feel. Too hard or too soft – blind testing is a must.
Hardness, friction, scenarios—ask before adjusting hardness
Three questions: what hardness, what scenario, what coefficient. One test: actual usage measurement—three questions and one test, the supplier's background is clear.
Anti-slip verification comes first: first determine whether the usage scenario is dry or wet, then discuss the hardness level—anti-slip is the partner of hardness.
Making sample retention a habit: retain a sample from each batch and retest the hardness by batch. Before switching materials for a new batch, compare first before scaling up—the batch stability is maintained, and customer complaints are fewer.
Slipping, Sticky, Abrasive: A Fault Comparison Table
| Phenomenon | Reason | Countermeasure |
|---|
| Somewhat hard | More filling | Come on |
| Somewhat soft | Oily | Add padding |
| Poor slip resistance | Low coefficient | Formulate a prescription |
| Feels light and floating | Batch bleaching | Lock window |
| Poor rebound | High hardness | Formulate a prescription |
A friction coefficient of 0.3 and 0.6 both feel 'not slippery,' but it's a different story when hands are wet. Slip resistance should be measured according to actual working conditions; don't just rely on the hardness chart, as the chart can't show differences with wet hands.
Hardness is a measure of hand feel, but not the whole scale. Both may be Shore A 70, yet SEBS is soft and sticky, while TPU is elastic and tough. The ruler is the same, but the feel is different. Don't place orders based solely on hardness.
Use ultra-soft glue for anti-slip mats, medium glue for handles, and hard glue for structural parts. Set the hardness grade according to the用途 (purpose), don’t apply one type of material to everything; if the softness and hardness are mismatched, the parts will be ruined.
The feel has to be evaluated through blind testing. Test three samples of the same hardness before scoring, and don't let the label 'soft is good' influence you. It's only considered acceptable if the blind test cannot distinguish the difference in hardness.
The friction coefficient is adjusted to the target value according to the scenario, and the batch hardness is controlled within ±3A. Anti-slip parts should not slip when held by hand or move when placed on the table. Only when a blind test with 20 people yields consistent scores will it be approved; if a batch drifts, it means customer complaints.
Hardness adjustment relies on adding oil and fillers, not changing the grade. Adding 5 parts of naphthenic oil reduces the Shore A by 5-8 degrees, and adding 20 parts of calcium carbonate increases it by more than 10 degrees. The texture changes from soft and smooth to rough, and excessive fillers cause the surface to appear hazy.
All are Shore A 70: SEBS-based is soft and sticky, TPU-based is tough and resilient, TPV is near rubber. Hardness is accurate when measured on a 6mm stacked sample; for thin pieces of 2mm, the reading is more than 5 degrees softer. If the thickness is insufficient during inspection, remeasure with stacked samples.
Measure slip resistance according to actual working conditions, don't just look at the hardness dial. A wet-hand friction coefficient ≥0.6 is considered slip-resistant; the dial cannot show the difference when hands are wet. Blindly testing three samples and then labeling the soft one as good is misleading.
Classify hardness by usage; you can't dominate everything with a single material, and using the wrong combination of soft and hard pieces will ruin it.
. After touching three samples of the same hardness, mark them separately and let the labels go along. Anti-slip needs to be measured according to the actual working conditions; don't just look at the hardness dial, the dial cannot show the difference when hands are wet.
Cologne Customer Case: Cost Overrun Leads to Soft Quotation, Custom Grades Return to Budget Line
A plastic injection processing factory in Xiamen had TPE material costs over budget, making their quotes uncompetitive. Cologne assisted in customizing special grades resistant to oil and temperature, bringing costs back within the budget line and making quotes competitive again. Customized according to working conditions, costs were initially saved through the formula—when costs exceeded the budget, first look at the formula system.
Summary
The process of TPE hardness adjustment: the scenario is decided first, then the hardness is adjusted. Friction coefficients of 0.3 and 0.6 are two different things for anti-slip; anti-slip relies on the partner.
There are always people asking: Can substandard materials actually be used?
Our answer has never changed—there are many places where it can be used, and not a single place where it can't be used can be touched. It is different from recycled material: one has the indicators off, the other has broken molecular chains.
