踩上去不滑不翘，验收测这四项
| 现象 | 参数 | 对策 |
|---|
| 熔接线 | 模温低 | 升模温 |
| 熔接线 | 料温低 | 升料温 |
| 气泡 | 干燥不足 | 加干燥 |
| 缩水 | 保压不足 | 加保压 |
表格读法：接缝线先摸深浅，模温料温一项项抬——熔接线发白变脆，多半是料没熔透就合模。
模温料温，是防滑垫的参数线。
只压价格不测摩擦，积水就起翘
坑一：直接换料。线痕一深就换料，十有八九白花钱——先把模温料温喂够，再谈是不是料的问题。
坑二：防滑漏测。打滑——防滑测试，必测。
坑三：耐水漏测。变形——耐水测试，必测。
摩擦系数、耐候、厚度——定料前问清
三问：模温多少、料温多少、防滑按什么标准。一验：实际使用实测——三问一验，供应商底细清楚。
参数验证要先行：接缝位置的模温和料温列成卡，逐机台核对。先查参数，再谈价格——模温料温，是防滑垫的参数线。
留样要成习惯：每批留样，防滑耐水按批次复测。批次换料先对比再放量——批次稳，客诉少。
滑倒、起翘、发霉：故障对照一张表
| 现象 | 原因 | 对策 |
|---|
| 打滑 | 防滑不足 | 加纹路 |
| 变形 | 耐水不足 | 换耐水料 |
| 熔接线 | 模温低 | 升模温 |
| 老化 | 耐晒不足 | 换耐晒料 |
| 批次漂移 | 配方波动 | 锁窗口 |
浴缸防滑垫湿态摩擦系数要够，材料主流 Shore A 50-60，带吸盘贴地。 站上去滑不滑，湿水才算数，干地测出来的防滑不作数。
人站进浴缸，脚下垫子一滑整个人打晃——防滑不是脚感，是安全。 湿手湿脚的件，摩擦系数低一点就是一次摔跤风险。
防滑垫用一阵就发霉发黏、吸盘翘边，不是没洗，是材料耐水防霉没做。 浴室常年潮湿，低析出加防霉处理一起上，不然垫子先长菌。
验收按湿态防滑、耐水浸泡、防霉三项：湿水测摩擦，泡水测变形。 吸盘贴合单独核，贴不牢的垫子本身就是滑倒源。
按湿态防滑加耐水防霉配料，垫子泡水不翘、湿脚踩上去不滑。 浴室“垫子打滑”“发霉”的客诉一起归零。
浴缸防滑垫泡水又踩，TPE 要防滑、耐水、不发黏，滑了就是安全问题。
湿水状态摩擦力是核心；选表面带纹路的防滑配方，踩上去不溜、久泡不软化塌边，和浴缸底贴牢不移位。
防滑垫是长期泡水件，耐水解和压变要核。 压变大的垫踩久了不回弹、纹路压平；每批测泡水后硬度和摩擦，批次换料先做湿滑摩擦对比。
浴缸防滑垫收尾验收：湿水摩擦、泡水回弹、贴底不移三项随批走。
每批留样测泡水后硬度和湿态摩擦，踩上不溜；批次换料先小批试水，不软化不滑动再出货。
科隆客户案例：阻燃不过检出口卡关，留样数据过检
上海一家家居日用厂，浴缸防滑垫阻燃不过检，出口卡关。科隆配合提供同批次留样与物性数据，阻燃等级过检，顺利出口。留样加数据，出口关一次过——阻燃问题，先看助剂体系。
小结
浴缸防滑垫的选型，参数先查，防滑再测，熔接线明显模温或料温没到位，模温料温是参数线。
A slip in the bathtub can lead to an injury accident. Non-slip mats lack sufficient static friction; saving on material costs ends up costing lives.
Slipping is not a trivial matter; first, check if the static friction is sufficient.
Bathtub anti-slip mats are 'slip-resistant and water-resistant items': slip-resistant, water-resistant, and mold-resistant. The material needs to be slip-resistant, water-resistant, and mold-resistant — conclusion first: SEBS-based TPE is mainstream for bathtub anti-slip mats; for high-end anti-slip mats, TPV composites are retained.
The biggest pitfall of bathtub non-slip mats: obvious weld lines, mold temperature or material temperature not in place. If the weld lines are obvious, first check the parameters—mold temperature and material temperature, which are the parameter lines for the non-slip mat.
Bathtub anti-slip mats are functional parts: cracking or slipping are all problems. Choosing the right material ensures bathroom safety—these are functional parts, don't skimp on the material cost.
Soaking in water and sun every day, why use TPE?
Reasons for using TPE for bathtub anti-slip mats: can provide slip resistance, can be water-resistant, can be mold-resistant, high efficiency — these four together make it suitable for anti-slip mats.
Anti-slip is key: slip-resistant when wet. Incorporate anti-slip testing into the acceptance—slipping is the problem.
Water resistance cannot be compromised: long-term soaking in water. Include water resistance testing in the acceptance—if it deforms, that's a problem.
Wet feet, soaking water, aging—what does each of the three checks test?
Slippery conditions: slip-resistant for wet conditions. Anti-slip data must be verified—slipping is a problem.
Water immersion condition: long-term water immersion. Water resistance data must be tested—deformation indicates a problem.
Sun exposure condition: Bathroom sun exposure. Sun resistance data needs to be tested—aging, that's the issue.
TPE mat versus PVC, which one to choose for the bathtub
| Dimension | SEBS-based TPE | PVC |
|---|
| Non-slip | Can be done | Can be done |
| Water-resistant | Good | Can be done |
| Mildew-proof | Can do | general |
| smell | Controllable | Yi has flavor |
| Cost | Medium-high | Low |
| Purpose | mainstream | Low price |
Table reading: PVC is cheap but has average odor and mildew resistance; TPE is water-resistant and mildew-resistant — for bathtub anti-slip mats, TPE is the mainstream choice.
Choose by positioning: mainstream TPE, low-cost PVC.
It doesn't slip or lift when stepped on; check these four items for inspection.
| Phenomenon | Parameter | Countermeasure |
|---|
| Fusion line | Low mold temperature | Mold Heating Temperature |
| Fusion line | Material temperature is low | Increase material temperature |
| bubble | Insufficient drying | Add drying |
| shrink | Insufficient pressure holding | Increase pressure |
Table reading: First feel the depth of the seams, then check mold temperature and material temperature item by item — if the weld line turns white and brittle, it is mostly because the material did not melt through before the mold was closed.
Mold temperature and material temperature are parameter lines of the anti-slip mat.
If you only press the price without testing for friction, accumulated water will cause it to warp.
Pitfall 1: Directly changing the material. If you change the material as soon as the flow marks get deep, you will most likely waste money—first, make sure the mold temperature and material temperature are adequate, then discuss whether it's really a material problem.
Pitfall 2: Missed anti-slip testing. Slippage—anti-slip testing is a must.
Pitfall three: Water resistance leakage testing. Deformation—water resistance testing must be conducted.
Friction coefficient, weather resistance, thickness—ask clearly before finalizing the material
Three questions: What is the mold temperature, what is the material temperature, and according to what standard is the anti-slip measured. One check: actual measurements during use—three questions and one check, the supplier's details are clear.
Parameter verification must come first: list the mold temperature and material temperature at the seam positions in a table, and check them machine by machine. First check the parameters, then discuss the price—mold temperature and material temperature are the parameter lines for the anti-slip mats.
Making sample retention a habit: retain samples for each batch, and retest slip resistance and water resistance batch by batch. When changing materials between batches, compare first before increasing the volume—stable batches result in fewer customer complaints.
Slipping, Warping, Mold: A Fault Comparison Table
| Phenomenon | Reason | Countermeasure |
|---|
| slip | Insufficient slip resistance | Add texture |
| Transformation | Insufficient water resistance | Change to waterproof material |
| Fusion line | Low mold temperature | Die temperature |
| Aging | Insufficient sun resistance | Change to sun-resistant material |
| Batch Drift | Formula fluctuation | Lock window |
The bathtub anti-slip mat must have a sufficient wet friction coefficient, with mainstream material Shore A 50-60, and attached to the floor with suction cups. It only counts if it doesn't slip when standing on it with water; slip resistance measured on a dry floor doesn't count.
A person steps into the bathtub, and if the mat underfoot slips, the whole body wobbles — anti-slip is not about feel, it’s about safety. When hands and feet are wet, even a slightly lower friction coefficient is a fall risk.
The anti-slip mat gets moldy and sticky, and the suction cups peel off after a while. It's not that it hasn't been washed; it's that the material wasn't treated for water resistance and mold prevention. Bathrooms are wet all year round; a low leaching and mold-resistant treatment should be applied together, otherwise the mat will grow bacteria first.
Acceptance is based on three aspects: wet slip resistance, water immersion resistance, and mildew resistance: friction is measured when wet, and deformation is measured after water immersion. Suction cups are checked individually; mats that do not stick firmly are themselves a source of slipping.
Made with ingredients that are slip-resistant when wet and water- and mold-resistant, the mat does not warp when soaked and is not slippery when stepped on with wet feet. Customer complaints about bathroom mats 'slipping' and 'molding' are completely eliminated.
The bathtub anti-slip mat is soaked and stepped on; TPE needs to be non-slip, water-resistant, and non-sticky. Slipping poses a safety issue.
Friction in wet conditions is key; choose a non-slip formula with a textured surface, so it doesn't slip when stepped on, doesn't soften or collapse after prolonged soaking, and stays firmly in place on the bathtub bottom.
Anti-slip mats are components that are soaked in water for long periods, so resistance to hydrolysis and compression deformation must be checked. Mats with high compression deformation will not rebound after being stepped on for a long time, and their patterns will be flattened; for each batch, measure hardness and friction after soaking in water, and when changing materials between batches, first compare wet slip friction.
Bathtub anti-slip mat final inspection: three items of wet friction, water immersion rebound, and sticking to the bottom without shifting are checked batch by batch.
For each batch, retain a sample to test water hardness and wet friction; step on it to ensure it is not slippery. When changing material for a batch, first test a small batch in water; do not ship until it is neither softened nor slippery.
Cologne Customer Case: Flame Retardant Failed Inspection, Export Blocked; Sample Data Passed Inspection
A household daily-use factory in Shanghai had its bathtub non-slip mats fail the flame retardant inspection, blocking export. Cologne cooperated by providing samples of the same batch and physical property data, passing the flame retardant grade inspection and allowing smooth export. With samples and data, the export inspection passed in one go — for flame retardant issues, first look at the additive system.
Summary
When choosing a bathtub non-slip mat, first check the parameters, then test the slip resistance. If the weld line is obvious, it indicates that the mold temperature or material temperature was not properly set. Mold temperature and material temperature are parameter lines.
