脚垫一粘一滑机身晃，气味还散不掉。笔记本脚垫析出没换对，软化油就是祸根。
结论先摆：笔记本脚垫，防滑析出绑一起
笔记本脚垫是“垫机身的件”：防滑、防震、不粘。材料要防滑好、低析出、低气味——结论先给：笔记本脚垫用 SEBS 基 TPE 是主流；低析出要求高，低油配方优先。
笔记本脚垫最大的坑：气味散不掉，软化油要换。气味和析出，根子都在油——软化油，就是隐形变量。
笔记本脚垫是体验件：粘、滑、气味都是投诉。材料选对，机身才稳——体验件，别省料钱。
TPE凭啥防滑：防滑随调，还低气味
笔记本脚垫用 TPE 的理由：防滑可调、低气味可做、效率高、成本可控——四条合起来，适合脚垫。
防滑是核心：机身放桌上不滑。摩擦系数按手感验——滑，就是体验杀手。
析出不能省：油往表面跑，粘灰发粘。析出测试（高温）写进验收——析出，就是隐形变量。
垫一天考它：静置、夏热、清洁
静置工况：天天垫。防滑、防震数据要验——滑，就是问题。
温度工况：机身发热。耐热、析出数据要验——发热析出，脚垫就粘。
清洁工况：擦拭清洁。耐污数据要验——粘灰，都是体验。
TPE还是橡胶：脚垫上看移不移位
| 维度 | TPE | 橡胶 |
|---|
| 防滑 | 可调 | 好 |
| 气味 | 可控 | 橡胶味 |
| 析出 | 可控 | 中 |
| 成本 | 低 | 中高 |
| 批次 | 稳 | 波动大 |
| 效率 | 注塑 | 硫化 |
表格读法：橡胶防滑好但气味和批次是短板；TPE 低气味、效率高——笔记本脚垫，TPE 是主流。
高防滑场景加高摩擦配方——按用途选。
两个坑：软化油外移、气味超标
坑一：软化油。油多软但析出，气味和发粘根子都在油——油种换对，气味才散。
坑二：气味超标。气味散不掉，体验差——气味等级写进验收。
坑三：防滑虚标。手感滑，机身晃——防滑按实测验收。
软化油查三处：析出、气味、硬度
三问：防滑按什么方法、析出按多少度、气味按什么标准。一验：实际放置实测——三问一验，供应商底细清楚。
气味验证要先行：气味等级先测。样垫贴鼻子闻、放热台一晚看粘不粘——油，就是开关。
留样要成习惯：每批留样，防滑析出按批次复测。批次换料先对比再放量——批次稳，客诉少。
机身晃就是滑：摩擦先测
软化油管理三查：查油种、查油量、查析出。三查住，机身发热也不冒油——三查住，气味才不返。
查油种：油种决定气味和析出。油种对齐，气味可控——油种，就是开关。
查油量：油量按配方窗口控。油多，析出多——油量，就是开关。
查析出：高温析出测试写进验收。析出过，油量就超——析出，就是裁判。
| 油管理 | 动作 | 说明 |
|---|
| 查油种 | 气味开关 | 低气味油 |
| 查油量 | 配方窗口 | 析出可控 |
| 查析出 | 高温测试 | 油量裁判 |
| 查批次 | 每批测 | 波动可控 |
表2读法：油三查加批次，一项不能少，发粘投诉才压得住。
| 材料指标 | 要求 | 说明 |
|---|
| 防滑 | 按手感 | 机身不滑 |
| 析出 | 高温测试 | 不发粘 |
| 气味 | 1-3 级 | 体验达标 |
| 批次 | 逐批稳定 | 手感一致 |
表3读法：四指标是脚垫的体检表。机身一晃，就露馅。
油种是气味的开关，换油比换香精管用。 样垫贴鼻子闻气味，放热台一晚看析出粘不粘，机身发热油析出累积。
析出粘滑是脚垫的体验杀手，油往表面跑就粘灰。 析出测试高温验，油多析出多，油种对齐气味才可控。
脚垫静置但天天受热，长期放置析出累积。 夏天发热加长期放置，双工况过了，复购率才上得来。
样垫闻气味、热台烤一晚看粘不粘——一嗅一烤见真章。 粘滑一次就露馅，机身一晃体验差一档。
脚垫是静置件，油种油量两头查。 气味、析出、温度一起控，复购率才压得下来。
脚垫气味看油种，软化油一换气味就下来。 样垫贴鼻闻再加 60℃ 热台烤一晚，粘滑粘灰就是析出，机身发热天天烘。
脚垫长期静置也析出，夏天发热加存放双重烘。 样垫热台烤一晚粘滑粘灰，油种对齐气味才可控。

The floor mat is sticky and slippery, causing the machine body to shake, and the smell won't go away. The notebook's foot pad has degraded and hasn't been replaced properly; the softening oil is the root of the problem.
Conclusion first: Laptop foot pads, anti-slip, tie together
Laptop foot pads are 'parts that pad the body': anti-slip, shockproof, non-sticky. The material should be highly anti-slip, low-exudation, and low-odor — conclusion first: SEBS-based TPE is the mainstream for laptop foot pads; high demand for low exudation, low-oil formulation is preferred.
The biggest drawback of notebook leg pads: the smell won't go away, and the softening oil needs to be replaced. The smell and exudation all stem from the oil—the softening oil is the hidden variable.
Laptop foot pads are experience parts: stickiness, slipperiness, and smell all lead to complaints. Choosing the right material ensures the stability of the machine — experience parts, don't skimp on material costs.
Why TPE is slip-resistant: slip resistance can be adjusted, and it also has low odor
Reasons for using TPE for laptop foot pads: adjustable anti-slip, low odor, high efficiency, controllable cost—these four combined make it suitable for foot pads.
Anti-slip is key: the body placed on the table should not slip. Check the friction coefficient by touch—slippery is a experience killer.
Precipitation cannot be skipped: oil runs to the surface, making the ash sticky. Precipitation test (high temperature) is written into acceptance — precipitation is an invisible variable.
Test it for one day: let it sit, summer heat, clean
Static condition: daily padding. Anti-slip and shockproof data must be verified—slipping is the problem.
Temperature conditions: the body generates heat. Heat resistance and precipitation data need to be verified—if heat causes precipitation, the foot pads will stick.
Clean condition: wipe clean. Stain resistance data needs to be tested—dust adhesion is all about experience.
TPE or rubber: check if the floor mats shift
| Dimension | TPE | Rubber |
|---|
| Non-slip | Adjustable | Good |
| smell | Controllable | Rubber smell |
| Precipitation | Controllable | middle |
| Cost | Low | Medium-high |
| Batch | Stable | Highly volatile |
| Efficiency | injection molding | Vulcanization |
Table reading: Rubber has good anti-slip properties but its smell and batch consistency are drawbacks; TPE has low odor and high efficiency — for laptop foot pads, TPE is mainstream.
High anti-slip scenario with enhanced friction formula — choose according to use.
Two issues: migration of plasticizer oil, excessive odor
Pitfall 1: Softening oil. No matter how soft the oil is, it will separate; the smell and stickiness are all from the oil — only by using the right type of oil will the smell dissipate.
Pitfall 2: Excessive odor. The smell doesn’t dissipate, resulting in a poor experience — record the odor level in the acceptance inspection.
Pitfall 3: Misleading anti-slip claims. Feels slippery, the body wobbles — test the anti-slip function in practice.
Check three aspects of softening oil: precipitation, odor, hardness
Three questions: What method is used for anti-slip, at what temperature does precipitation occur, and what standard is used for odor? One verification: Actual placement and measurement — three questions and one verification make the supplier's background clear.
Odor verification should be done first: smell levels are measured first. Take a sample pad, hold it to the nose to smell, leave it on a heating platform overnight to see if it sticks—oil is the switch.
Making sample retention a habit: retain samples for each batch, and re-test for anti-slip precipitation by batch. When changing batch materials, compare first before scaling up—stable batches lead to fewer customer complaints.
If the body shakes, it slides: test friction first
Three checks for softening oil management: check the type of oil, check the amount of oil, check for separation. With the three checks in place, the machine body heats up but does not leak oil — with the three checks in place, the smell will not return.
Check oil type: The type of oil determines the smell and precipitation. When the oil types are aligned, the smell is controllable — oil type is basically the switch.
Check the oil amount: The oil amount is controlled according to the formula window. More oil results in more separation — the oil amount is the switch.
Check and analyze: High-temperature precipitation tests are written into the acceptance. If precipitation occurs, the oil volume exceeds — precipitation is the referee.
| Oil management | Action | Explanation |
|---|
| Check oil type | Odor switch | Low-odor oil |
| Check oil level | Recipe Window | Precipitation controllable |
| analyzed and extracted | High temperature test | Fuel Judge |
| Check batch | Test each batch | Fluctuations controllable |
Table 2 reading: Check the oil three times and add the batch, not a single item can be omitted, only sticky complaints can be suppressed.
| Material specifications | Requirement | Explanation |
|---|
| Non-slip | Feel the touch | The body is not slippery |
| Precipitation | High temperature test | Does not stick |
| smell | Levels 1-3 | Experience Standard Reached |
| Batch | Stabilize batch by batch | Consistent feel |
Table 3 Reading: The four indicators are the check-up form for the floor mats. As soon as the body shakes, the flaw is exposed.
The type of oil is the switch for the smell; changing the oil is more effective than changing the fragrance. Place a sample pad under your nose to smell the scent, leave it on a heating table overnight to see if it exudes stickiness, and check if oil accumulates as the machine body heats up.
Exuded stickiness is a killer for the foot mat experience; when the oil spreads to the surface, dust sticks. In exudation tests under high temperatures, the more oil, the more exudation. Only by aligning the oil type can the smell be controlled.
The floor mats remain stationary but are exposed to heat every day, gradually releasing and accumulating substances over time. In summer, with heat and long-term placement, only after both conditions are met can the repurchase rate increase.
Smelling the mat and baking it on a hot plate overnight to see if it's sticky—one sniff and one bake reveal the truth. If it's sticky and slippery, the filling shows after just one try; if the machine shakes, the experience drops a notch.
Floor mats are stationary parts, and the type and amount of oil are checked at both ends. Odor, precipitation, and temperature are controlled together, only then can the repurchase rate be reduced.
The smell of the floor mat depends on the type of oil; changing the softening oil will reduce the smell. Place the sample mat near the nose and then bake it on a 60°C hot plate overnight. Stickiness and dust adhesion indicate exudation, and the device should be heated daily.
Floor mats will exude even after long-term static storage. In summer, the combination of heat and storage accelerates exudation. Bake the sample mat on a hot plate overnight to see stickiness and dust adhesion; the smell can only be controlled if the oil type matches.
Cologne Client Case: Flame Retardant Failed Inspection, Export Blocked, Reformulation Passed Inspection
A consumer electronics manufacturer in Chengdu found that laptop footpads failed the flame retardant inspection, blocking exports. Cologne cooperated in reformulating the recipe (oil/additive/filler ratio), achieving the required flame retardant level, and exports proceeded smoothly. Reformulating the recipe allows passing the flame retardant check in one go — flame retardancy is a matter of formulation, not the brand substitution.
Summary
For small items like laptop footpads, the oil determines the smell, and any movement of the device will reveal flaws.
We never guess three things: temperature resistance, lifespan, and cost.
No usage temperature provided, we don’t guess; no service life provided, we don’t guess; no dosage provided, we don’t guess either. The solutions guessed will eventually require rework and claims returned.
