Is environmentally friendly hot melt adhesive really environmentally friendly? Hot melt adhesive has fast bonding speed, stable performance, and is conducive to sustainability. Automation technology tells operators that it is highly cost-effective. And in the process of using hot melt adhesive, there is no need for a drying process, the bonding process is simple, the range of materials that can be bonded is wide, and the bonding compressive strength is good.
However, hot melt adhesive is a chemical product. The main components are EVA, rubber, polyolefin, and polyamide as the theme materials, produced using thickening resins and softeners. Our common medical supplies, such as shoes, hats, bags, etc., are very common in daily life. Hot melt adhesive is used for daily chemical packaging, label tape, etc.
In fact, environmentally friendly hot melt adhesive is non-toxic, pollution-free, and easy to package, transport, and store. It is an environmentally friendly chemical material that is deeply loved by the public. The international hot melt adhesive environmental testing project includes ROSE standards, formaldehyde testing, determination of 18 polycyclic aromatic hydrocarbons, halogen fluorine, chlorine, bromine, iodine content, determination of perfluorooctane sulfonate (PFOS) content, determination of nonylphenol polyvinyl chloride ether (NDEOS) content, and REACH84 testing. Medical hot melt adhesive has also passed the skin insensitivity test.
Of course, it cannot be ruled out that environmentally friendly hot melt adhesive manufacturers in the market use a large amount of non environmentally friendly and cost-effective materials in order to reduce costs, resulting in their hot melt adhesives being recognized as environmentally friendly. Friendly products.
What issues should be considered when using EVA hot melt adhesive? Although there are various types of hot melt adhesives, there are five key factors that can affect their performance. Consider these items before applying hot melt adhesive to ensure ideal performance: Temperature When using EVA hot melt adhesive, ensure that it can fully wet […]
First of all, the conclusion is that the powder on gold and silver cardboards is mostly due to “surface coating not being treated properly” or “glue temperature not being pressed down” Gold and silver cardstock is coated with a layer of gold and silver foil or PET aluminum plated film on the surface of the […]
Our common hot melt adhesive can generally stick to wood, paper (white cardboard, kraft paper, silver cardboard, PE coated paper, BOPP coated paper), cloth (non-woven fabric, cotton), glass, acrylic, plastic (PVC, PP, PE, etc.), metal (aluminum alloy, iron plate, stainless steel, etc.). Easy to stick: wood, white cardboard, kraft paper, non-woven fabric, cotton cloth, glass, […]
The use of hot melt adhesive requires appropriate preparation and preheating to ensure smooth operation. 1. Glue Add an appropriate amount according to the amount of glue used and the size of the hot melt glue pool. During normal use, maintain a liquid level range of 35% -80% in the sol tank. If the amount […]
