This section is the stick of ordinary PC material, not a control device. Stick hardness (not easy to break.) Self-defense: Beat broken free replacement, self-defense must be defense to share, we all know the rubber material Easy to bend Smell and hardness is not enough, Life is not long, Harmful to human body. This section is PC material does not smell, no harm to the human body.
Polycarbonate (referred to as PC) is the molecular chain containing carbonate groups High molecular weight polymer , According to the structure of ester groups can be divided intoAliphatic , Aromatic, aliphatic-aromatic, etc. Among them, aliphatic and aliphatic-aromatic polycarbonates Mechanical behavior Lower, thus limiting its presence Engineering plastics At present, only the aromatic polycarbonate obtained industrial production.
PC is a linear carbonated polyester, the molecular carbonate groups and other groups are arranged alternately, these groups can be aromatic, PC is a colorless glassy amorphous polymer with good optical properties. PC high molecular weight resin has a certain toughness, cantilever notched impact strength of 600 ~ 900J / m, unfilled brand of heat distortion temperature of about 130 ° C, glass fiber reinforced can increase this value by 10 ° C. PC bending modulus of up to 2400MPa or more, the resin can be processed into large rigid products below 100 ° C, under load creep PC poor hydrolysis resistance, can not be used to repeat the subject to high-pressure steam products.
PC material has Wear resistance.
The main advantages:
1, with strength and elastic modulus, impact strength, wide temperature range;
2, transparency and free dyeing;
3, forming shrinkage is low, good dimensional stability
4, good fatigue resistance;
5, good weather resistance;
6, excellent electrical characteristics;
7, tasteless odorless harmless to the human body. The main performance:
A, mechanical properties: high strength, fatigue resistance, dimensional stability, creep is also small (high temperature conditions are rarely changed);
B, heat aging: the enhanced UL temperature index of 120 ~ 140 ℃ (outdoor long-term good aging);
C, solvent resistance: no stress cracking;
D, on the water stability: high temperature water easily decomposed (high temperature and high humidity environment to be used with caution);
