Q:How can the strength and toughness of plastic products be tested simply?
Testing of universal material testing machine: tensile strength, elongation at break and bending strengthImpact testing: impact strength
Q:How much is plastic PP5 resistant to cold?
Ordinary homopolymer PP has higher heat resistance, but when it reaches -20 degrees of low temperature, it will not stand, easy to brittle.
Q:How can a plastic foam be used?
The bubble can be shattered after. During the Christmas season. The snow scene is beautiful and true feeling. Some sell porcelain shop with foam and newspaper wrapped easily broken porcelain porcelain can prevent rupture.
Q:What kind of plastic material is special for microwave oven?
Use: the only plastic box that can be placed in a microwave oven. It can be reused after careful cleaning. Special attention should be paid to some microwave oven boxes. The box is made of No. 5 PP, but the box cover is made of No. 1 PE. Because the PE can not withstand high temperature, it can not be put into the microwave oven with the box.

Although some plastic products also say that you can use microwave heating, such as "5" PP material.But my advice is not to use plastic as much as possible.

I suggest you still use high temperature resistant glass or ceramic products!
Q:What are the characteristics of plastic products?
Three indispensable synthetic materials in daily life. Specifically, the plastic is made of natural or synthetic resin as the main ingredient, adding various additives, in certain conditions such as temperature and pressure can be made into a certain shape, keep shape materials at room temperature.

LDPE (low density polyethylene): common plastic film, plastic film and so on. High temperature will produce harmful substances, plastic film into the microwave.
Q:What is the difference between plastic PP1, PP2, PP3 and PP4?
PP1 plastic centrifuge tube is made of PP material, without toxicity and chemical tolerance. PP2 heat resistant aging. PP3- use overview: endoscope casing, left and right toolbox, door handle remarks: weathering, heat aging.
