It can be said that EVA materials are still very popular in the 21st century. EVA materials are widely used in various electronic industries and other related industries. Now the demand for EVA materials will continue to rise in the future.
1. Excellent heat resistance of EVA material: foaming corner is usually used at 80t, foaming Px instrument can withstand 70-80 ℃, and foaming PP can withstand 120t. Foaming PP in
Leave at 120 degrees Celsius for 21 hours. The size shrinkage is less than 2%, and the foam PE shrinks by about 40% under phase condition. Therefore, foaming PP can be used for the use of temperature * 100t occasions.
2. EVA material with excellent mechanical properties: Take the Ace type EVA foam material of Koha Electric Company of Japan as an example. Its mechanical properties such as tensile strength and tearing strength are
A higher grade of foamed plastics; Its compression strength ** rigid PUR and foam Ps. Compared with soft PUR, Dong has medium compression strength;
3. EVA material significant insulation: foamed PP and foamed PE - like is a closed bubble structure, therefore, its thermal conductivity will not be affected by solid moisture, because its thermal conductivity is lower than foamed PE, has significant insulation, so it can be used as the best insulation material.
4. EVA material with resilience has high impact energy absorption capacity.
5. The chemical corrosion resistance of EVA material is better than all other foam plastics; Edible resistant oil to meet the needs of sleeve greasy food packaging.
6. EVA material has good stress cracking resistance.
7. EVA material foam PP compared with foam PS, combustion without gas release.
8. EVA material can also be recycled.
