Application of Exxelor in environmental adhesive

With the development of petroleum industry, adhesives have been widely used in various industries, including automobile industry, electronic appliances, medical equipment, wood, shoe-making, textile, industry and other industries, providing conditions and guarantee for the rapid development of the national economy. However, when the adhesive industry drives the economic growth, it also brings various environmental pollution problems: a large number of solvent volatilization in the adhesive The use of additives not only harms people's physical and mental health, but also destroys the ozone layer. Therefore, the development of environmental friendly adhesives is an inevitable trend in the future adhesive industry, Development trend of environmental friendly adhesives: water-based, solvent-free, solid, low toxicity, recycled adhesive, inorganic adhesive, etc. hot melt adhesive, which is 100% solid because it does not contain solvent, has become the mainstream direction of environmental adhesive research and development.

The hot melt adhesive is mainly composed of adhesive, tackifier, filler, antioxidant and other additives. The adhesive is composed of thermoplastic resin or rubber. According to the main material, it can be divided into polyolefin, polyester, polyamide, polyurethane, polyethylene vinyl acetate hot melt adhesive.

Exxerortm is a series of functional products which are grafted with maleic anhydride by melt method from polyolefins such as elastomer, polypropylene and high density polyethylene. Because of its polar and non-polar properties, exxelortm is commonly used in polyolefin and polyester hot-melt adhesives to improve the bonding strength and bonding strength of hot-melt adhesives to refractory materials, including metal, glass, polyolefin, nylon and wood Paper, etc.

For polyolefin hot melt adhesive, because it has no polarity, it can only be bonded to non-polar materials, and its adhesion to metal, wood, paper, glass, nylon and other polar materials is poor. The application range of polyolefin hot melt adhesive is limited by the performance of the material. The application range of polyolefin hot melt adhesive is greatly expanded by introducing polar materials to modify polyolefin hot melt adhesive.

The adhesive strength of polyolefin hot melt adhesive with exxelortm as main resin or modifier can improve the bonding strength of metal, PA and other polar materials. Exxelortm modified hot melt adhesive can be applied to aluminum plastic pipe and nylon pipe for oil and gas transportation, with long-term and effective anti-corrosion function; it can also be used for extrusion of multi-layer pipe, adhesive layer in composite film, adhesive layer in composite plate molding, clothing and footwear, furniture, powder coating, packaging adhesive and other products, so it is widely used in packaging, automobile, industry and textile , construction and other industries.
