Advantages of EVA foam:

EVA rubber and plastic products are environmentally friendly plastic foam materials, which have advantages such as good cushioning, seismic resistance, thermal insulation, moisture resistance, chemical corrosion resistance, and do not absorb water.

EVA rubber and plastic products are designed to be processed and shaped, and their shockproof performance is better than traditional foaming materials such as polystyrene (foam), and they meet the environmental requirements, so they are a good choice for export products. Compared to shockproof packaging, it can be cut and formed; Due to significant differences in density, it can also have more applications.

EVA, commonly known as foam, is an environmentally friendly packaging material. It is made of EVA foam. Overcoming the shortcomings of ordinary foam adhesive such as fragility, deformation, and poor recovery. It has many advantages such as water and moisture resistance, shock resistance, sound insulation, insulation, good plasticity, strong toughness, recycling, environmental protection, collision resistance, and strong anti slip and shock resistance. It also has good chemical resistance and is an ideal substitute for traditional packaging materials.

2: According to the density (hardness) of its products, it can be divided into 25 degrees, 38 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, and 80 degrees; According to the color of its products, it can be divided into various colors such as black, white, white, black, gray, yellow, green, red, coffee, orange, etc. (which can be foamed according to international color standards).

The thickness mainly includes: 0.3MM-60MM, and the thickness tolerance is generally around plus or minus 0.1MM

There are various thicknesses, densities, and colors to choose from, which can be rolled or molded into various shapes. The rubber pad has weather resistance, chemical resistance, buffering, sound absorption, and superior adhesion. It can be used in various styles such as insulation rubber pad, EVA rubber pad, etc. 1. The characteristic of EVA resin is that it has good properties, rubber like elasticity, and can still have flexibility at (50 ℃), good properties and surface gloss, good chemical properties, and resistance.

Usage:The product is applied to electronic and electrical products, mechanical components, various small household appliances, mobile phone accessories, industrial appearance, computer and peripheral equipment, automotive accessories, audio and video devices, toys, cosmetics, craft gifts, medical instruments, power tools, work stationery, shelf display, home decoration, acrylic glass, ceramic products, and transportation insulation, posting, sealing, anti-skid, buffering, and shockproof packaging.

Due to the ease of crosslinking of the copolymer of fire-resistant EVA foam products, the ability to fill a large amount of fillers without brittle cracking, and the ability to maintain comprehensive mechanical properties, fire-resistant EVA foam products are suitable for cable insulation materials. Typical applications of fireproof EVA foam products include heat shrink insulators, semiconductor insulators, and flame retardant insulators. Because fireproof EVA foam products have good foaming performance (with an appropriate amount of foaming agent added), while fireproof EVA foam products have resilience, aging resistance, and crack resistance.

At the same time, Kunshan Jiashunda adhesive products have small and even bubbles, so the products of Dongguan Chemical Research Institute are used as foam boards for insoles and other foam bodies, such as child wheels, sound insulation boards, auto parts, pedals, gymnastics pads, yacht protection boards, etc. Fireproof EVA foam products can be made into hot melt adhesive for wireless binding in the printing industry, packaging of cardboard boxes, sealing of cardboard boxes, label bonding, furniture corner bonding and assembly, automotive product assembly, cellulose film, polyester film, PVC film can be bonded. This adhesive has the advantages of short curing time and production, making it suitable for automated production lines.

The fine foaming process of EVA foam is based on practical experience in foam foaming. In addition, the quality control and defect correction on the foaming site can also affect the processing performance and product performance. PVC resin with a narrow molecular weight distribution is better, so that the processing performance and product performance are more uniform, which is conducive to controlling the processing conditions and product quality. Low molecular weight will reduce the thermal stability, aging performance, mechanical properties, etc. of the product, but high molecular weight will make it difficult to uniformly plasticize during processing, resulting in a serious decrease in the internal and external quality of the product. When severe, particles or "fish eyes" may appear The plasticization time of PVC resin is also an important selection indicator.

Adjustment of conventional foam formula: adjustment of special foam formula, analysis of common defects and corrective measures. 1. Adjust the conventional foam formula at material temperature of 18-20 The formula for cylindrical foam with a foaming diameter of 2 meters and a height of 1 meter under the reference condition of 20 ℃ is called the reference formula. The commonly used reference formula is shown in Table 1.0. A small particle size also has a certain impact on plasticization, reducing the friction between particles and prolonging the plasticization time. Therefore, it is required that the resin has good fluidity, larger particle size distribution, narrow particle size distribution, high viscosity PVC powder, and compact PVC powder are not conducive to the full foaming of the foam.

The product features are:; The structure is fine, the surface is smooth, and elastic, with good shockproof, moisture-proof, and wear-resistant effects, which can effectively protect your product from harm. EVA foot pads, also known as EVA rubber pads for industrial use, are composed of EVA foam and double-sided adhesive. EVA foam is used as the substrate, and one or both sides are bonded to domestic oil glue or 3M, NITTO Nippon, TESA Desa, SONY Sony, DIC Japan, Hib.

fiveThermal insulation, thermal insulation and low temperature performance, can withstand severe cold and exposure. 6. Sound insulation, sealed foam, good sound insulation effect. This product is used for packaging aids, such as electronics, electrical appliances, communication products, computer peripheral equipment, component support pads, mobile phones, LEDs, lighting, furniture, machinery, toys, hardware, aquarium, plastics, crafts, stationery, glass, gifts, home appliances, speakers, computers, digital products, cars, etc.

It does not contain water or solvents, does not require drying, does not cause expansion and deformation of the adhesive, does not cause solvent poisoning and ignition problems, and is convenient for storage and transportation. Modified asphalt can improve the temperature sensitivity (ciliarity at low temperatures and viscosity at high temperatures), stiffness, and impact performance of asphalt. It has been applied in fields such as civil engineering, roofing materials, paving materials, etc.
