产品详细信息

原装pom，pom安全带扣具有耐磨性

1。POM也是一种典型的热敏塑料，在240°C下会严重分解。在210℃下，停留时间不能超过20分钟；即使在190℃下，停留时间也不应超过1h。因此，在保证注射过程中材料流动性的前提下，应尽量选择较低的成型温度和较短的加热时间

2。聚甲醛具有明显的熔点，均聚物聚甲醛为175℃，共聚物聚甲醛为165℃。在成型过程中，筒体温度分布在前段190～200°C，中部为180～190°C，后部为150～180°C，喷嘴温度为170～180°C。薄壁制品的筒体温度可适当提高，但不能超过210°C.
BR/> 3。POM吸湿性低，树脂在加工前可能不会干燥。如有必要，可在90～100℃下干燥2～4h

Virgin pom with wear sistance for pom Seat belt buckle

1. POM is also a typical heat-sensitive plastic, which will decompose severely at 240 ° C. At 210 ℃, the residence time cannot exceed 20min; even at 190 ℃, the residence time should not exceed 1h. Therefore, under the premise of ensuring the fluidity of the material during injection, the lower molding temperature and shorter heating time should be selected as much as possible.

2. POM has obvious melting point, homopolymer POM is 175 ℃, copolymer POM is 165 ℃. During molding, the distribution of barrel temperature: 190-200 ° C in the front section, 180-190 ° C in the middle section, 150-180 ° C in the rear section, and the nozzle temperature is 170-180 ° C. For thin-walled products, the barrel temperature can be increased appropriately, but it cannot exceed 210 ° C.

3. POM has low hygroscopicity, and the resin may not be dried before processing. If necessary, it can be dried at 90 ～ 100 ℃ for 2 ～ 4h.
