| 塑料路沿石模具一般呈凸字形，是塑料颗粒经高温溶化注塑加工而成，原料主要采用 聚丙烯，具有无毒、无味，密度小，强度、刚度、硬度耐热性均优于低压聚乙烯,可在100度左右使用。具有良好的电性能和高频绝缘性不受湿度影响。 Plastic roadside stone moulds are generally convex shaped, which are made of plastic particles by high temperature melting and injection molding. The raw materials are mainly polypropylene, which is non-toxic, odorless, low density, superior to low-pressure polyethylene in strength, stiffness and hardness, and can be used at about 100 degrees. Good electrical performance and high frequency insulation are not affected by humidity. |
