Foam Hand,Victory Foam Hand,Cube Stress Balls ,Round Cube Stress Ball are made of EVA foam material and following is the intruduce and advantage of material
EVA rubber and plastic products are new environmentally friendly plastic foaming materials, which are made of eva plastic raw materials. It overcomes the shortcomings of ordinary styrofoam, such as fragility, deformation and poor recovery. It has many advantages such as good cushioning, shock resistance, sound insulation, heat insulation, moisture resistance, chemical resistance, good plasticity, toughness, recycling, impact resistance, non-slip, non-toxic, non-absorbent, etc., and good chemical resistance , Is an ideal alternative to traditional packaging materials. And meet environmental requirements, is a good choice for export products.
EVA material hardness: 18-28 degrees high foam, 25 degrees high elastic material 38 degrees, 45 degrees packaging materials, 50 degrees, 55 degrees laminated materials, 60 degrees 70 degrees 80 degrees commonly used in machinery, EVA harder the more expensive, Shaw Hardness measurement. Error range: ± 3 ℃, generally use a measuring instrument to test.
EVA material color: usually black and white, color can be customized according to customer requirements. The general colors are light gray, dark gray, sky blue, dark blue, beige, yellow, orange, pink, red, light green, dark green, light purple, dark purple, and brown. Any color on the international color card can be customized.
EVA material specifications: sheet 1m * 2m, 1.2m * 2.5m, 1m * 3m, 1.2 * 3m, 1.4 * 3m, 1.4 * 3.5m, 1.4 * 3.3m, 1.4 * 3.8m, 1.5 * 4.1 meters, 1.4 * 3.8 meters, 1.5 * 3.5 meters, 1.5 meters * 3 meters, 1.52 * 3.0 meters, coils can be cut into coils of any length after trimming and high temperature welding, and the thickness can be cut according to customer requirements When it is 0.5mm ~ 60mm, it can be laminated, double-sided adhesive tape, and the width can be divided into several pieces.
Thickness: not less than 0.5mm, not more than 95mm (the whole board), the specifications of EVA corresponding to different materials / hardness are different, and the error range is ± 0.2mm.
EVA material features: water resistance, corrosion resistance, shock resistance, thermal insulation, sound insulation, etc.
Water resistance: closed cell structure, no water absorption, moisture resistance, good water resistance.
Corrosion resistance: Corrosion resistance to seawater, grease, acid, alkali and other chemicals, antibacterial, non-toxic, odorless, and pollution-free.
Processability: Easy for hot pressing, cutting, gluing, laminating, etc.
Anti-vibration: high resilience and anti-tension, strong toughness, and good shock / buffering performance.
Thermal insulation: excellent thermal insulation, cold insulation and low temperature performance, can withstand severe cold and exposure.
Sound insulation: closed cells, good sound insulation.
EVA material quality classification: Buyers about the quality classification of EVA material, we are here to introduce a preliminary, EVA material is divided into three grades divided into A grade B grade C grade.
Grade A materials are brand new materials and do not contain old materials and recycled materials. The most intuitive way to distinguish them is to look at the color, white is enough, white is black, black is not enough. Second, look at the air holes, because the addition of foaming air holes of the recycled materials will be relative to A It's rough; press three fingers and press hard to see the rebound effect. Material A has a taste but belongs to the kind of floating package that is floating on the surface and left in a ventilated place for a while. Can be exported to the EU to pass the environmental protection SGS certification, widely used in children's toys, electronics, machinery.
Material B also has a taste, but it also belongs to the kind of floating package that is open on the surface and left in a ventilated place for a period of time. The taste can basically be dissipated. It can also pass through SGS. Material A was so white that it looked dull. The intuitive difference between material A and material B is color and density.
The C material is fully recycled, which is the so-called recycled material. It is intuitively distinguishable by color and smell.
Use of EVA material: Widely used in shockproof and anti-slip of electronic appliances, sealing and heat preservation, metal can lining of various packing boxes and other industries. Products are widely used in: instruments, gifts, printing, packaging, machinery, tablet computers, mobile phones. Digital cameras. air conditioning. Drinking fountains. computer. Electronics. communication. Military products. Speaker. Lighting. Toys and other industries. Production and further processing of stationery supplies, travel supplies, children's toys, handmade DIY products for preschool education, EVA packaging products, etc. (EVA, RB, PU, latex foam), laminated fabrics, adhesives and other materials, such as composite sheets , Forming, laminating, and so on. Products are widely used in shoes, luggage, packaging, sports equipment, hats, toys, clothing, bedding, decorative materials, sofa materials, car mattresses, inner canopies, communication equipment, household appliances, electronics industry, computers, hardware tools , Medical instruments, instruments, furniture, toys, crafts, tourism products, cultural supplies, cosmetics and so on. Play a shield. Anti-static, fire-proof, shock-proof. Insulation and non-slip. fixed. Wear-resistant and heat-resistant. Insulation and other effects.
Application fields of EVA materials:
Field 1: Because EVA material has strong softness, chemical resistance and good elasticity, it is widely used in soles and interior materials of various footwear.
Field two: eva material has the inclusiveness and crosslinkability that other materials do not have. Because of its properties, it is suitable for halogen-free flame-retardant cables, semiconductor shielded cables and two-step silane crosslinked cables It is also widely used in industrial and manufacturing supplies due to its performance.
EVA material quality assurance: The surface of the EVA material produced by our factory has no pores / no pungent taste, and our ordinary materials can pass the environmental protection test standard (some foamed EVA materials have gray-black surface and dense surface Steam pores of different sizes have a strong pungent taste. This material is foamed from recycled materials and is harmful to the human body. Please choose carefully.)
Product molding quality assurance: According to the samples confirmed by the customer, the business and workshop production team leader handed over some problems encountered during the proofing process to avoid appearing in the large goods. The customer's requirements and precautions for the product are given as examples. The production team leader can only sign after confirming that they are fully aware. During the period of making the goods, the workshop quality staff and the production team leader will randomly check the quality of the product. Before packaging, there is a special quality staff to perform a full check into the box. After triple inspection, quality customers can rest assured. Supply EVA products of various colors, hardness and specifications, shockproof, waterproof, non-slip, strong elasticity, suitable for products such as inner care, footwear, packaging, sports goods and other industries.
