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。

小结
笔记本脚垫这类小件，油是气味的开关，机身一晃就露馅。
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 leached and wasn't replaced correctly; the softening oil is the root of the problem.
Conclusion first: Laptop foot pads, anti-slip, tie together
Laptop foot pads are 'components 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; for high low-exudation requirements, low-oil formulations are preferred.
The biggest problem with 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: adjustable anti-slip, and low odor
Reasons for using TPE for notebook 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 killer for the experience.
Precipitation cannot be skipped: oil runs to the surface, making sticky 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 odor 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 and excessive odor
Pitfall 1: Softening oil. No matter how soft the oil is, it will separate; the smell and stickiness are all rooted in the oil—only by changing to the correct type of oil will the smell go away.
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. Place the sample pad on your nose to smell, leave it on a hot plate overnight to see if it sticks — oil, that's the switch.
Making sample retention a habit: retain samples from 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 engine body gets hot 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. Align the oil type, and the smell can be controlled — the oil type is 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 included in the acceptance. If precipitation occurs, the oil amount 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 oil three times and add the batch, not a single item can be missing, only then sticky complaints can be controlled.
| Material specifications | Requirement | Explanation |
|---|
| Non-slip | By touch | The body is not slippery |
| Precipitation | High temperature test | Does not stick |
| smell | Level 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. When the body shakes, the flaw is revealed.
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 platform 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 pad experience; when the oil spreads to the surface, dust sticks. In exudation tests under high temperatures, the more oil exudes, the more intense it is, and the type of oil must be aligned for the odor to be controllable.
The floor mats remain stationary but are exposed to heat every day, gradually releasing and accumulating over time. In summer, with heat and prolonged placement, only after both conditions are met can repurchase rates 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 time, and 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 all controlled together, only then can the repurchase rate be lowered.
The smell of the floor mats depends on the type of oil; changing the softening oil will remove the smell. If you stick the mat to your nose and then bake it on a 60℃ hot plate overnight, stickiness and dustiness are just the result of exudation, and the machine heats up if baked every day.
The floor mats will exude substances even if left standing for a long time, and in summer they are subjected to both heating and storage. The sample mats are baked on a hot plate overnight, becoming sticky, slippery, and dusty, and only when the type of oil is aligned can the odor be controlled.
Cologne Customer Case: Flame Retardant Failed Inspection, Export Blocked, Reformulated to Pass Inspection
A consumer electronics factory in Chengdu had notebook foot pads that failed the flame retardant test, causing an export block. In Cologne, the formula (oil/additive/filler ratio) was readjusted, the flame retardant level passed inspection, and the product was successfully exported. With the formula readjusted, the flame retardant passed the inspection in one go—the flame retardancy is a formula issue, not something that can be faked by just changing the grade.
Summary
For small items like notebook foot pads, oil is the switch for the smell, and a shake of the machine body will reveal the problem.
