EVA foam raw materials and foaming process

    1. EVA foam characteristics

    EVA foam is divided into environmentally friendly EVA, ordinary EVA (usually called b material), high elastic EVA, antistatic EVA (with antistatic agent), fireproof EVA (with flame retardant), high hardness EVA, etc.

    EVA has strong plasticity: it can be die-cut into any shape, various EVA packaging linings, EVA toys, EVA foot pads, EVA balls, EVA tubes, EVA adhesive products, EVA pencil cases, EVA printing, EVA flocking, Can be customized according to customer drawings.

    The composite of EVA and other materials: EVA can be single-sided and double-sided adhesives according to customer requirements, and the adhesives include ordinary adhesives, reinforced adhesives, high temperature resistant adhesives, fireproof adhesives, imported double-sided adhesives, and can be divided into pieces according to customer requirements after gluing Roll into any width and length. It can be single-sided and double-sided gold-plated silver powder, single-sided and double-sided with the same fabric, PU leather, plastic sheet, pearl cotton and other materials composite molding, also can be surface printing, silk screen, flocking, etc.

    Because it has good moisture-proof and shock-proof properties, and is designed to be processed into shape, it is often used in toolboxes, packaging boxes and other linings, and is also often used in environmentally friendly toys or other craft products.

2. EVA foam material and foam

    EVA, commonly known as foam, is a new type of environmentally friendly packaging material. It is made of eva foam. It overcomes the shortcomings of ordinary styrofoam that are fragile, deformed and poor in recovery. It has water-proof and moisture-proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, and impact resistance. It has many advantages such as strong anti-skid and shock resistance, and also has good chemical resistance. It is an ideal substitute for traditional packaging materials.

    3. How to foam EVA foam

     How to foam EVA foam, eva foam foaming process: the foaming agent releases a large amount of gas at the decomposition temperature to form a foam core. After the pressure is released suddenly, the release of the foam core causes the EVA and other materials to expand and form foam material. The advantages of EVA foam: EVA rubber and plastic products are new environmentally friendly plastic foam materials, which 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 shaped, and their shockproof performance is better than traditional foam materials such as polystyrene (foam), and it meets environmental protection requirements. It is a high-quality choice for export products.
