温度

湿度

光照

与

臭氧

影响 控制

高温（>30℃）加速橡胶氧化和热老化，导致硬

化、开裂（如丁腈橡胶在50℃下寿命缩短50%）

低温（<5℃）可能使弹性体变脆，低温取出时需

回温至20℃再使用

储存温度范围： 5℃~25℃ ，避免热源（如暖气、

阳光直射）

低温储存区需配备温控设备，避免温度波动

湿度>70%易导致冷凝水，加速水解（如聚氨酯在

潮湿环境中寿命缩短30%）

过度干燥（<40%）可能引发橡胶表面脆化。

相对湿度维持40%~65% ，使用除湿机或干燥剂

定期检查仓库防漏，避免地面返潮

紫外线（UV）引发橡胶光氧化，导致表面龟裂

（如EPDM暴露于UV下1年硬度增加20%）

臭氧（O₃）破坏橡胶分子链，尤其对氟橡胶、硅

胶影响显著

使用防紫外线包装 （如红色/橙色PE膜、不透光

铝箔）

远离高压电器、汞灯等臭氧源，仓库窗户涂覆防

UV涂层

Temperature

Humidity

Light

and ozone

Effect Control

High temperature (>30°C) accelerates rubber oxidation and

thermal aging, resulting in hardening and cracking (e.g., nitrile

rubber is shortened by 50% at 50°C)

Low temperature (<5°C) may make the elastomer brittle, and it

needs to be warmed to 20°C before use

Humidity > 70% can easily lead to condensation and accelerate

hydrolysis (e.g., polyurethane life in humid environment is

shortened by 30%)

Over-drying (<40%) can lead to embrittlement of the rubber

surface.

Ultraviolet (UV) light (UV) induces photooxidation of rubber,

resulting in surface cracking (e.g., 20% increase in hardness of

EPDM in 1 year when exposed to UV rays)

Ozone (O₃) destroys the rubber molecular chain, especially on

fluoroelastomer and silica gel

Use UV-resistant packaging (e.g. red/orange PE film, opaque

aluminum foil)

Keep away from ozone sources such as high-voltage appliances

and mercury lamps, and apply anti-UV coating to warehouse

windows

The relative humidity is maintained at 40%~65%, and a

dehumidifier or desiccant is used

Regularly inspect the warehouse for leaks to avoid moisture

return on the ground

Storage temperature range: 5°C~25°C, avoid heat sources

(such as heating, direct sunlight)

The cryogenic storage area needs to be equipped with

temperature control equipment to avoid temperature

fluctuations

氧气加速橡胶氧化，导致弹性下降（如NBR氧化

电离辐射（如γ射线）破坏分子结构，引发脆化

密封保存（真空或氮气包装），减少氧气接触

禁止存放于放射性物质或X射线设备附近

拉伸、压缩或悬挂导致永久变形（如O型圈压缩率

>30%后回弹率下降50%）

盘卷储存不当可能引发聚氨酯、夹布橡胶内部裂纹

平放储存，使用原厂支撑架或防变形托盘

禁止悬挂，聚氨酯、PTFE等材料需完全松弛状态

存放

油脂、溶剂（如汽油、四氯化碳）引发溶胀或化

学降解（如PU接触油类后体积膨胀40%）

金属接触：铜、铁等释放金属离子加速橡胶老化

Thin-walled seals with a thickness of < 1.5 mm need to be shortened by 50%.

The validity period of the assembly (e.g. gleering) is based on the shortest material

(e.g. NBR PTFE is calculated according to NBR)

注：

储存操作规范

STORAGE PRACTICES

Packaging requirements

The original sealed packaging shall not be opened, and PE/aluminum foil bags or

vacuum cans shall be used.

Multiple packages need to be separated to avoid contamination between materials

(e.g. PU and NBR cannot be mixed)

Inventory management

First-in, first-out principle: Inventory that has not been used for more than 12 months

needs to be re-inspected.

Periodic inspection: Hardness and surface condition are checked every 6 months

(visual hardness tester)

Transport protection

Use a shock-resistant foam box to avoid falling and squeezing.

It is forbidden to transport radioactive materials and chemicals in the same vehicle.

Disposal of failed seals

Mild aging (surface microcracks): can be downgraded for non-critical areas.

Severe aging (volume expansion, fracture): Treat as hazardous waste, and direct

discarding is prohibited

包装要求

原厂密封包装不得拆封，使用PE/铝箔袋或真空罐。

多件包装需分隔，避免材料间污染（如PU与NBR不可混装）

库存管理

先进先出原则：超过12个月未使用的库存需重新检验。

定期检查：每6个月检查硬度、表面状态（目视+硬度计）

运输防护

使用抗震泡沫箱，避免跌落、挤压。

禁止与放射性物质、化学品同车运输。

失效密封件的处置

轻度老化 （表面微裂纹）：可降级用于非关键部位。

严重老化 （体积膨胀、断裂）：按 危险废物处理，禁止直接丢弃
