Name: Plastic PVC Flat Washers
Size:M2,M3,M4,M5,M6,M8,M10,M12
Material: PA66, PA+50%GF, PA+50%GF, PEEK, PVDF, PPS, PTFE, PP, PVC, PC.
Polyvinyl chloride (PVC) flat washers for the color of yellowish translucent, glossy. Transparency is better than polyethylene and polypropylene, worse than polystyrene, with different amounts of additives, divided into soft and hard PVC; soft products are soft and tough, with a sticky feel; hard products, the hardness is higher than the low-density polyethylene but have lower than polypropylene, in the folding at the phenomenon of whitening.PVC material flat washer is a kind of use of a chlorine atom instead of polyethylene in the hydrogen atom of a polymer material parts.
High surface hardness and excellent scratch resistance; surface resistance value of 10 6 ~ 10 8 times ohm, with excellent anti-static function, impact resistance, and chemical solvent resistance is outstanding; beautiful appearance, very flat and smooth; light transmittance of 73% or more.
Flame retardant grade is ul-94v-0.
It has excellent chemical stability, corrosion resistance, high hardness, high strength, UV protection (aging resistance), fire-resistant and flame retardant (with self-extinguishing), reliable insulating properties, smooth and flat surface, non-absorbent and non-deformation, easy to process and so on.
Color: transparent, smoke, milky white, grey, etc.
1. Mechanical properties: PVC flat washers have high hardness and mechanical properties. It increases with the increase of molecular weight but decreases with the increase of temperature. Hard PVC flat washers have good mechanical properties, with a modulus of elasticity of up to 1500-3000 MPa. while the soft PVC elasticity is 1.5-15 MPa. but the elongation at break is as high as 200% -450%. PVC flat washer friction in general, with a static friction factor of 0.4-0.5 and a dynamic friction factor of 0.23.
2. Thermal properties: PVC flat washer's thermal stability is very poor, 140 ℃, which is the beginning of decomposition, and a melting temperature of 160 ℃. PVC material has a small coefficient of linear expansion, flame retardant, and oxidation index of up to 45 or more. Therefore, it is necessary to add heat stabilizers in the process to ensure the performance of the product.
3. Electrical properties: A PVC flat washer is a polymer with good electrical properties, but due to its own polarity, its electrical insulation is not as good as that of PP and PE washers.
Product Specification
A flat washer made of PVC is a lightweight, strong, and durable part, which is waterproof and moisture-proof, anti-corrosion and wear-resistant, beautiful and generous, and at the same time easy to process, economical, environmentally friendly, and safe.
1. A flat washer made of PVC is a kind of polyvinyl chloride material parts with good weather resistance and corrosion resistance, which can be used outdoors for a long time.
