Anshan henkel food-grade plastic dealers anshan henkel food-grade plastic dealers can test result is pressure sensitive adhesive
stick 5 ball.
Packing books with join softening point low viscosity regulator, can achieve good bonding when penetrating, stick to the purpose.
Appearance white granular pale yellow flakes anshan henkel food-grade plastic dealers in the following table: the composition of pressure sensitive adhesive.
44, hot melt adhesive, observe whether there is a powdery material after melting, if there are captions powdery material packing, adhesive performance is poor.
Melting point (
84, 65 -
78 anshan henkel food-grade plastic dealers bouquet: odor gas + =.
Basic resin hot melt adhesive is the basic resin of ethylene and vinyl acetate copolymerization under high temperature and high pressure, which EVA resin.
The viscosity of 2500 -
3500, 5500 -
6500 anshan henkel food-grade plastic glue gun dealers is to use the principle of heating melting glue and the glue, this feature makes the glue gun itself in part of the heating temperature is very high, must be protected when using, or exposed to high temperature part is easy.
The smell of hot melt adhesive from the hot melt adhesive itself, is the essential characteristics of hot melt adhesive, from raw materials, production process, the influence of the circulation.
Sour, sweet, bitter, spicy, salty, is to be mixed, by feeling or sense of smell and feel.
Hardness is 78 -
82, 65 -
75 this kind of resin is the main components of the production of hot melt adhesive, the proportion of basic resin, quality determines the basic properties of the hot melt adhesive, (
Such as adhesive bonding ability, melting temperature and the cohesive strength)
18 - generally choose the VA content
33, refers to (
800, VA content is low, the higher the degree of crystallinity increase hardness, same case VA content, low crystallinity increase elasticity, EVA melt refers to the choice is very important also, investment refers to the smaller illiquid strength high melting temperature of the adhesive wetting and permeability is quite poor.
In the logistics transportation of hot melt adhesive, may also be dyed into new smells.
Anshan henkel food-grade plastic dealers in the production process, hot melt adhesive may also have new odor source, through the production process control can achieve the goal of reducing odor.
