This section is a common PC material stick, not a control device. Stick hardness is superb (not easy to break.) Self-defense: hit people to fight free of charge returned, self-defense to share, we all know rubber material Easy to bend Smell and hardness is not enough, Life is not long, Harmful to the human body.This section is a PC material without smell, no harm to the human body.
Polycarbonate (PC) is a carbonate chain in the molecular chain Polymer , According to the structure of ester groups can be divided intoAliphatic , Aromatic, aliphatic-aromatic and the like, in which, due to the aliphatic and aliphatic-aromatic polycarbonate Mechanical behavior Lower, thus limiting its presence Engineering plastics The application of aromatic polycarbonate is currently only available for industrial production.
PC is a linear carbonated polyester in which the carbonic acid groups are alternately arranged with other groups, which may be aromatic, PC is almost colorless glassy amorphous polymer, good optical properties. PC high molecular weight resin has a certain toughness, cantilever notched impact strength of 600 ~ 900J / m, unfilled grade heat distortion temperature is about 130 ° C, the glass fiber can increase this value by 10 ° C. PC bending modulus up to 2400MPa or more, the resin can be processed into large rigid products. Less than 100 ° C, the creep under load The PC is poorly hydrolyzable and can not be used to repeat products subject to high pressure steam.
PC material with Wear resistance.
1, with strength and elasticity coefficient, impact strength, the use of a wide temperature range;
2, transparency and free dyeing;
3, forming shrinkage is low, the size of good stability
4, good fatigue resistance;
5, good weather resistance;
6, excellent electrical characteristics;
7, tasteless and odorless to the human body harmlessMain performance:
A, mechanical properties: high strength, fatigue resistance, dimensional stability, creep is also small (high temperature conditions are rarely changed);
B, heat aging resistance: enhanced UL temperature index of 120 ~ 140 ℃ (outdoor long-term good aging);
C, solvent resistance: no stress cracking;
D, the water stability: high temperature water easily decomposed (high temperature and high humidity environment to be used with caution);
