Shanghai Daoqin Plastics Co., Ltd.

Polyplastics plastics 株式会社(Polyplastics Group) launch 改良版 terephthalic acid ester (PBT), is series high pressure automotive parts provide high resistant electrical property can. Duranex PBT CG7030 is 30% 玻璃 filling product, property high, electrical retardant and electrical property can non stability.

automotive industry positive in 经历巨 large 变化, due to full world in force decrease/reduce use 化石燃 material and reduce amount, electrical 动出行 day to heavy 视. automotive manufacturing 商逐渐 toward electrical 动化转 type, for high pressure parts demand expected will increase. Polyplastics plastics in lower 40°C to 140°C temperature degree ring in, for polyamide (PA) (PA)66 and PBT材 material 进行 广泛 testing, application in battery, rate control mono 元(PCU) and electrical machine /发 electrical machine and other electric vehicles parts in.

in high temperature and wet ring in, PBT材 material property can 几乎没 has 变化. therefore, Polyplastics plastics is, it ratio PA66 more combined in high pressure ring in use. this table/sheet 明, ring 境发生变化时, use PBT can decrease/reduce electrical property can 变化.

Duranex PBT CG7030 tool has high property. Polyplastics plastics 称, PBT材 material wet rate and rate large is PA66-GF33% 十 separation 之一.

another, testing 结果显示, in high temperature and wet ring in (85oC/85%RH, 1000 small rear), Duranex PBT CG7030 can maintain electrical strong/high degree. is, PA66-GF33% in ring in strong/high degree decline 40% left right.

and PA66-GF33% versus ratio, Duranex PBT CG7030 volume resistivity has improve/increase. in high temperature and high wet degree ring lower, PA66-GF33% volume resistivity obvious decline.
