What unknown facts about foam do you know?
Do you know all these unpopular facts about foam?
EVA foam is a new type of environmentally friendly material. It is a product of foam and is also called EVA sponge. It is made of eva foam. It overcomes the shortcomings of ordinary foam rubber such as brittleness, deformation and poor recovery. It has many advantages such as water and moisture proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, impact resistance, anti-skid and shockproof ability, etc. It also has good chemical resistance and is an ideal traditional packaging material. alternatives.
EVA foam can be produced in the required colors according to different requirements. It is divided into A material, B material, C material, low-odor environmentally friendly material and non-environmentally friendly material.
EVA foaming process
The foaming agent releases a large amount of gas at the decomposition temperature to form a bubble core. After a sudden pressure relief, the bubble core releases pressure and causes EVA and other materials to expand, forming foaming materials.
EVA foam foam material grade
Class C, Class B, Class A, Class 3A, CR material, high elastic EVA material, rubberized EVA material, etc. It is often used in the lining of tool boxes and packaging boxes, and is also commonly used in environmentally friendly toys and craft products.
Advantages of EVA foam
EVA rubber and plastic products are new environmentally friendly plastic packaging materials that have the advantages of good cushioning, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, etc., and are non-toxic and non-absorbent. EVA rubber and plastic products are designed to be processed and formed. Their shock-proof performance is better than traditional packaging materials such as polystyrene (foam), and they meet environmental protection requirements. They are the best choice for export products. Compared with shock-proof packaging, it can be cut and formed; due to the large density difference, it can also have a wider range of uses.
Automobile
Automobile lightweighting has always been a major direction for the future development of automobiles, and it is also a major factor in solving the cruising range of new energy vehicles. Replacing steel with plastic has achieved great success in lightweighting automobiles. The low density and low cost of polymer foam materials can fully meet the trend of lightweight and cost reduction in automobile development. In addition, the flexibility and softness of the foam material provide additional comfort. Relevant data shows that by 2022, the global automotive foam materials market is expected to reach US$35.38 billion, with an average annual compound growth rate of 9.4%.
Mobile terminal
With the advent of the full-screen era, today’s smartphones are becoming thinner and thinner in design, so the process requirements for mobile phone components are becoming more and more stringent. In order to meet the changing needs and expectations of the market, major mobile phone manufacturers have Cotton exhibitors have also been constantly exploring new application possibilities to bond different smartphone components to meet the more stringent requirements of mobile phone tapes, which have better shock resistance, waterproof and dustproof performance.
