摘要： PURPOSE: To provide a composite polymer material having extremely excellent mechanical properties e.g. elasticity, strength, dimensional accuracy, etc. within an ultra-low temperature range, by compounding a polymer with a flaky powder having particular shape at a specific weight ratio.
CONSTITUTION: A composite polymer material having excellent mechanical properties at an extremely low temperature, i.e. at ≤-100°C, is prepared by compounding (A) 20W50wt% of flaky powder (e.g. mica) having a weight-average aspect ratio of ≥15 and a weight-average flake diameter of ≤35μm and (B) 80W50wt% of a polymer (preferably having a flexural strain at break of ≥1% measured in liquid nitrogen, e.g., polyethylene, nylon 6, polycarbonate resin, etc.).

摘要： PURPOSE:To achieve a diaphragm plate having a high rigidity rate without anisotropy while keeping characteristics of polyester, by composing a specific amount of mica powder of a specific shape to a polyester or polyamide system polymer. CONSTITUTION:Mica, =10 weight average aspect ratio is composed to a polyester system polymer such as an alkyleneglycolester polymer of telephthalic acid or isophthalic acid, or a polyamide polymer obtained from polymerization of lactam or aminocarbonic acid and polymerization/condensation of diamine and dicarbonic acid. The mixing rate of mica powder is 30-95wt% of polyester or polyamide system polymer and 5-70wt% mica, taking into account the rigidity rate and sheet forming performance. Thus, a diaphragm plate without anisotropy and with high rigidity is obtained.
