Household Scrubs PP Cutting Board Cut Fruit Plate Antibacterial Skid

Type:Chopping Blocks
Material:Plastic
Goods Brief: pp material, non-slip and easy to clean, burr-free transparent thin section, is unlikely to remain, cutting board with cut fish, cut fruit, etc., convenient health

PP attributes:
1) Physical properties: polypropylene (PP) is non-toxic, odorless, tasteless milky white highly crystalline polymers, density of only 0.90 ~ .091g / cm3, it is one of the lightest of all the plastic variety. It particularly stable water, water absorption in water 24h of only 0.01%, from about 8 to 150,000 molecular weight. Moldability is good, but the shrinkage, thick-walled products easy to depression. (PP) products surface gloss, easy coloring.
2) Mechanical Properties: polypropylene (PP) of high crystallinity, regular structure, which has excellent mechanical properties, its strength and hardness, elasticity than HDPE, but at room temperature and low temperature, due to the regularity of the molecular structure itself high impact strength is poor so that, when the molecular weight increases, impact strength also increases, but the molding processability is deteriorated. The most outstanding performance PP is bending fatigue resistance, as with a living hinge integrally PP injection, can withstand 7 × 107 times opening and closing folding bending without signs of damage, dry friction coefficient and nylon are similar, but in oil lubrication, as nylon.
3) Thermal properties: PP has good heat resistance, melting point at 164-170 deg.] C, products can be sterilized at a temperature above 100 ℃, without outside in, 150 ℃ not deformed. Brittle transition temperature of -35 ℃, below -35 ℃ embrittlement occurs, cold resistance than polyethylene.
4) Chemical Stability: polypropylene (PP) good chemical stability, in addition to be concentrated sulfuric acid, concentrated nitric acid erosion, but a variety of other chemical reagents are relatively stable, but the low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons and chloro hydrocarbons, etc. can make PP soften and swell, while its chemical stability also improved with increasing degree of crystallinity, it is suitable for the production of polypropylene pipes and fittings of various chemical, anti-corrosion effect is good.
5) electrical properties: polypropylene (PP) high-frequency insulation performance, because it almost does not absorb water, so the insulation performance is not affected by humidity. It has a high dielectric constant with increasing temperature, the heat can be used to produce electrical insulation products, it is also high breakdown voltage, suitable for electrical accessories. Anti-voltage arc resistance, static high copper contacts easy to aging.
6) Weather resistance: polypropylene (PP) is very sensitive to ultraviolet light, adding zinc oxide, dilauryl thiodipropionate, carbon black or similar creamy white fillers to improve its anti-aging properties.
