PA11 D40【PA11 D40】PPO的介电常数和介电损耗在工程塑料中是***小的品种之一，几乎不受温度，湿度的影响。可用于低、中、高频电场领域（介电常数越小，绝缘性越好）PPO的负荷变形温度可达190℃以上，脱化温度-170℃。
The dielectric c***tant and dielectric loss of PPO is one of the ***all *** varieties in engineering plastics, and is hardly affected by temperature and humidity. It can be used in low, medium and high frequency electric field (the ***aller the permittivity, the better the insulation). The load deformation temperature of PPO can reach above 190 degrees, and the temperature of dehydration is -170.
PP化学改性创造新材料化学改性不仅可以改变一种树脂的性能，而且可以制造出新品树脂材料。一些目前经常用到的树脂材料就是通过改性得来的，比如超高分子量聚乙烯(UHMPE)即是化学改性的产物。这种超高分子量聚乙烯极大地提高了HDPE材料的机械性能。它的耐磨性和自润滑性超过其它工程塑料，机械性能和耐腐蚀性不亚于聚四氟乙烯(PTFE)。物理改性共混改性把树脂与其它一种或多种物料通过机械方式进行共混以达到某些特殊要求，这种方式就是共混物理改性。共混改性不能改变分子构型，但可以赋予材料新的性能。
PP chemical modification to create new material chemical modification can not only change the performance of a resin, but also create new resin materials. Some of the resin materials currently used frequently are modified, such as ultra high molecular weight polyethylene (UHMPE), which is the product of chemical modification. This ultra high molecular weight polyethylene greatly improves the mechanical properties of HDPE materials. Its wear resistance and self lubricity are higher than other engineering plastics, and its mechanical properties and corrosion resistance are no less than that of PTFE. The physical modification of the blend modifier to blend the resin with other or more materials by mechanical way to achieve some special requirements, this way is the physical modification of blending. Blending modification can not change the molecular configuration, but it can give the material new properties.

PC plastics introduction /PC plastics (polycarbonate)
英文名称:Polycarbonate 聚碳酸酯是日常常见的一种材料。由于其无色透明和优异的抗冲击性，日常常见的应用有光碟，眼镜片，水瓶，***玻璃，护目镜、***防***之玻璃、车头灯等等、动物笼子宠物笼子等。 聚碳酸酯PC‖也是笔记本电脑外壳采用的材料的一种，它的原料是石油，经聚酯切片工厂加工后就成了聚酯切片颗粒物，再经塑料厂加工就成了成品，从实用的角度，其散热性能也比ABS塑料较好，热量分散比较均匀。
English Name: Polycarbonate polycarbonate is a common material. Because of its colorless transparency and excellent impact resistance, daily common applicati*** include optical discs, glasses, water bottles, bulletproof glass, goggles, glass, headlights and so on, and animal cage pet cages. Polycarbonate PC is also a kind of material used in the outer shell of notebook computer. Its raw material is oil. After processing by polyester chip factory, it becomes polyester chip particles, and then processed by plastic factory, it becomes finished. From practical point of view, its heat dissipation performance is better than that of ABS plastic, and the heat dispersion is more uniform.

POM☆造成中国POM☆产能增长不能满足市场需求的原因是：其它国POM☆市场增长较快，而中国POM☆生产的基础比较薄弱；另外POM☆是资金和技术密集型的材料类化工产品，中国巨大的市场引起了国外大的关注，其它国一直想以其产品占据中国市场，不愿转让技术，使中国POM☆的技术水平提高缓慢.
POM, the reason that the growth of China's POM production capacity growth can not meet the demand of the market is that the market growth of other countries POM is faster, and the basis of China's POM production is relatively weak; in addition, POM is a capital and technology intensive material chemical product, and the huge market in China has aroused great attention from foreign countries, and other countries h***e always wanted to use it Products occupy the Chinese market, unwilling to transfer technology, so that the technological level of China's POM is slowly raised.

SBS鞋底式样可为半透明的牛筋底或色彩鲜艳的双色鞋底，也可制成发泡鞋底。用SBS制成的价廉的整体模压帆布鞋，其重量比聚***树脂鞋轻15-25%,摩擦系数高30%，具有优良的耐磨性和低温柔软性。SBS所具有这些优良性能，使得它在制鞋业中的应用十分广泛。
The SBS sole type can be translucent beef tendon bottom or brightly colored two shoe sole, and also can be made into foamed sole. The low price, integral molding canvas shoes made of SBS are lighter 15-25% than PVC resin shoes, with a high friction coefficient of 30%, with excellent wear resistance and low softness and softness. SBS has these excellent properties, making it widely used in shoemaking industry.
