Plastic tableware compared with metal, stone, wood, plastic products has the advantages of low cost and strong plasticity.
1. Light weight: Plastic is a lightweight material with a relative density of 0.90 to 2.2.
2. Excellent chemical stability: The vast majority of plastic acid, alkali and other chemical substances have good corrosion resistance.
3. Excellent electrical insulation properties: Ordinary plastic is a poor conductor of electricity, its surface resistance, volume resistance is very large, with a figure of up to 109 A 1018 ohm.
4. a poor conductor of heat, with the effect of noise reduction and shock absorption: Generally speaking, the thermal conductivity of plastics is relatively low, equivalent to the steel 1/75 – 1/225
