In the current rapid development of the social environment, logistics transportation, express and other industries inevitably use PE based materials of ordinary express bags and anti-counterfeiting express bags, at the same time, the application of environmental protection hot melt pressure sensitive adhesive in the express bag adhesion just greatly improve the production efficiency of this […]
Pressure sensitive adhesive is a kind of adhesive which is sensitive to pressure. The pressure sensitive adhesive can form a relatively strong bonding force under a small force. The bonding force formed between the two surfaces is mainly van der Waals force and other polar forces. Therefore, after the formation of the adhesive surface, the […]
Using cyclopentadiene compounds as raw materials, petroleum resins can be obtained by thermal polymerization or cationic polymerization, and dicyclopentadiene petroleum resins are more common. Dicyclopentadiene petroleum resin is a light yellow to brown-yellow thermoplastic solid with a molecular weight between 300 and 3000. It can be used in the fields of road marking paint, adhesives, […]
Pressure sensitive adhesives are prepared by combining silicone elastomer materials with viscosifying resins, including silicone viscosifying resins. Such as US patents 5,237,082(Leir et al.),5,264,278(Mazurek et al.),5,264,278(Mazurek et al.),5,314,748(Mazurek et al.), and 5,514 ,730(Mazurek et al.). Silicone elastomer materials in pressure-sensitive adhesives have been prepared by polymerization of silicone compounds with end-alene unsaturated groups using actinic […]
Ordinary microwave oven door paste is made of transparent polyester film with a thickness of 0.1mm coated with acrylic solvent pressure-sensitive adhesive after drying and releasing polyester film composite, the final die-cutting molding. The appearance requirements of microwave oven door stickers are transparent and clear, and there should be no scratches, bruises, bubbles, and other […]
