零下二十度雪镜带一折就断
滑雪装备是“零下作业的件”:耐寒、防滑、韧性。材料要耐寒、防滑、韧性好——结论先给:滑雪装备用 TPU 是主流;高寒装备,SEBS 基 TPE 复合留。
滑雪装备最大的坑:温度高10度,寿命短一截。耐温每高10度,寿命就短一截——耐低温,是滑雪装备的寿命线。
滑雪装备是功能件:开裂、发硬都是问题。材料选对,滑雪才稳——功能件,别省料钱。
滑雪装备为什么偏向 TPU
滑雪装备用 TPU 的理由:耐寒好、韧性好、防滑好、效率高——四条合起来,适合滑雪装备。
耐寒是核心:零下环境。低温测试写进验收——开裂,就是问题。
韧性不能省:低温冲击。低温弯折测试写进验收——发脆,就是问题。
低温冲击防滑,三道关
低温工况:零下作业。耐寒数据要验——开裂,就是问题。
冲击工况:摔倒冲击。低温韧性数据要验——发脆,就是问题。
防滑工况:雪地行走。防滑数据要验——打滑,就是问题。

At minus twenty degrees, ski goggles break with just a fold; in the ski resort, it’s all down to luck. Ski equipment hasn’t been made resilient enough for low temperatures, so hitting the slopes is a gamble.
At minus twenty degrees, ski goggles break with just one fold
Skiing equipment is an 'item for sub-zero operations': cold-resistant, non-slip, and tough. The materials need to be cold-resistant, non-slip, and tough — here's the conclusion first: TPU is mainstream for skiing equipment; for high-cold equipment, SEBS-based TPE composites are used.
The biggest pitfall of ski equipment: 10 degrees higher in temperature, a shorter lifespan. For every 10 degrees higher in temperature resistance, the lifespan is shortened — low-temperature resistance is the lifeline of ski equipment.
Skiing equipment is functional: cracking and hardening are both problems. Choose the right materials to ski safely—these are functional parts, don’t skimp on the material cost.
Why is ski equipment inclined towards TPU
Reasons for using TPU in ski equipment: good cold resistance, good toughness, good slip resistance, and high efficiency — together, these four make it suitable for ski equipment.
Cold resistance is key: sub-zero environments. Low-temperature testing is written into the acceptance criteria—cracking is the problem.
Resilience cannot be compromised: low-temperature impact. Low-temperature bending tests should be included in acceptance — if it becomes brittle, it's a problem.
Low-temperature shock anti-slip, three checkpoints
Low-temperature conditions: operations below zero. Cold resistance data must be tested—cracking is the issue.
Impact conditions: fall impact. Low-temperature toughness data must be checked—if it becomes brittle, it's a problem.
Anti-slip condition: walking on snow. Anti-slip data must be tested—slipping is the problem.
TPU or SEBS base? See clearly at a glance
| Dimension | TPU | SEBS base |
|---|
| Cold-resistant | Good | Can do |
| Resilience | Good | middle |
| Non-slip | Good | Can do |
| Cost | Medium-high | middle |
| Wear-resistant | Strong | middle |
| Purpose | Main selection | Compound |
Table reading: TPU has good cold resistance and toughness but is expensive; SEBS has high cost-performance — for ski equipment, TPU is the mainstream.
Choose by part: outer shell TPU, inner lining SEBS-based.
Ski Equipment Inspection: The Low Temperature Test
| Temperature | Test | standard |
|---|
| -10℃ | Bend | through |
| -20℃ | Bend | through |
| -30℃ | Bend | through |
| -40℃ | Bend | Reference |
How to read the table: Measure low temperatures level by level, and you can see the lifespan—- bend at -20°C, -30°C step by step, and you’ll have a clue once the level starts to harden.
Cold resistance is the lifespan line of skiing equipment.
Only reporting normal temperature, all three high-cold pits exploded
Pitfall 1: Only reports room temperature. Soft at room temperature, hard below zero, cracks after just one use in the snow — must test at low temperatures.
Pitfall 2: Resilience missed in testing. Brittle — low-temperature bending must be tested.
Pitfall three: slipping undetected. Slipping — anti-slip test, must be tested.
When choosing ski materials, first determine low-temperature resistance
Three questions: What temperature is used for cold resistance, what standard is used for low-temperature bending, and what surface is used for anti-slip. One test: actual skiing test——three questions and one test, the supplier's details are clear.
Low-temperature testing must come first: perform bending and impact tests according to the actual low temperatures of the ski resort; don't use room temperature data as a substitute. Test the low temperature first, then talk about the price—low-temperature resistance is the lifeline of ski equipment.
Making sample retention a habit: retain samples for each batch and retest cold resistance and toughness by batch. When changing materials for a batch, compare first before scaling up—the more stable the batch, the fewer the customer complaints.
Ski equipment: Don't panic if something goes wrong, match each item correctly
| Phenomenon | Reason | Countermeasure |
|---|
| Cracking | Insufficient cold resistance | Switch to cold-resistant material |
| becoming crispy | Insufficient resilience | Switch to high toughness material |
| slip | Insufficient slip resistance | Change the pattern |
| become hard | Low-temperature aging | Switch to low-temperature resistant material |
| Batch difference | Formula Drift | Lock window |
Ski equipment can bend at low temperatures of -30°C without cracking, while for extremely cold conditions it needs to reach -40°C. For every 10°C increase in temperature, aging accelerates by one grade, shortening its lifespan.
TPU has good cold resistance and toughness but is expensive, while SEBS offers a higher cost-performance ratio but has moderate cold resistance. Outer shell TPU, inner lining SEBS-based — selected according to the part.
Ski equipment becoming stiff is not due to material aging, but due to insufficient low-temperature toughness. When it cracks under impact from falls, first check the low-temperature toughness before looking at the normal temperature strength.
Ski Equipment Inspection: low-temperature bending, low-temperature impact, snow slip resistance, comprehensive snowfield environment. Snow goggles with frame and lenses are fed part by part, and UV, humidity, and low temperature are tested together.
-30℃ bend without cracking and passed low-temperature impact testing, ski equipment does not crack or slip in winter. Samples from each batch are tested for cold resistance and toughness, and protective gear is supplied according to the complete set list.
Ski equipment is tested for -30°C low-temperature bending and low-temperature impact, as brittleness is the most deadly in the snowfield. The TPU shell has superior cold resistance and toughness, while the SEBS lining offers high cost performance, and the goggles have the frame supplied according to part.
Snow traction is tested according to the actual coefficient of friction, and the coupling of ultraviolet, humidity, and low temperature is tested once. Protective gear linkage is configured according to the complete set list, and low-temperature brittleness is checked against the lowest temperature of the site.
Test cold resistance and toughness on samples from each batch.
The component series is supplied as a complete set, and snow goggles with frames are matched according to the linkage list. Samples from each batch are retained to test cold resistance and toughness, and snow field ultraviolet, humidity, and low temperature coupling are tested once and discarded. Brittle behavior at low temperatures is verified according to the lowest temperature on site.
Cold-resistant components should be tested according to the site's minimum temperature, not just normal temperature strength. The shell is TPU with SEBS lining, fed according to parts. Snow, ultraviolet, humidity, and low-temperature coupling tests are conducted once. Protective gear linkage is according to the complete set checklist.
Each batch retains sample cold resistance and toughness.
Cologne Customer Case: Bulk Delamination of Coating, Adjusting Parameters to Replicate Benchmark
A sports equipment factory in Jiaxing experienced batch delamination of ski equipment overmolded parts, with a high rework rate. Cologne assisted in adjusting injection molding parameters (mold temperature/material temperature/holding pressure), eliminating delamination and reproducing the sample’s tactile rebound. The parameter window was locked to address delamination at the source—the overmolding issue, first checking parameters and then the substrate.
Summary
When selecting ski equipment, test it in low temperatures first, then check its toughness. A 10-degree increase in temperature shortens its lifespan. Resistance to low temperatures is the lifeline of durability.
