Sheet machine, plastic raw materials performance and usage ( C)

Plastic machinery manufacturing the product or material has been our most buildings in a city, daily necessities, often supplies an important ingredient in or packaging, and through the system cup machines produce commodity plastics machinery is our current packaging materials and use of the most widely used products. Here continue to introduce sheet machine, plastic raw materials of other properties and USES: ( 3) Good ability of resistance to chemical corrosion. Plastic to acid, alkali, salt and other chemicals are corrosion resistant ability. Ptfe is the most stable chemical properties of plastics, its chemical stability than all known materials ( Including gold and platinum) 。 The most commonly used corrosion resistant materials for hard PVC, it can be resistant to the concentration of 90% sulfuric acid, various concentration of hydrochloric acid and alkali, is widely used to produce chemical pipes and containers, such as using the box the machine production snack box is a kind of practical products. ( 4) Insulation performance is good. Plastic for electricity, heat, have good sound insulation performance, is widely used to make electrical insulating materials, insulation materials, and sound insulation materials. Superior plastic electric insulation performance and low dielectric loss performance, can be comparable to ceramic and rubber. Besides used as insulation, is now producing semiconductor plastic magnet, conductive plastic, etc. , which nurtures the unique significance to the development of electronic industry.
