Recently, the weather has been extremely hot, and many customers have reported that the hot melt adhesive used before has problems such as softening, easy drawing, and easy to burst; Adhesive is a kind of hot adhesive widely used in industry, and its applicability is unmatched by many other adhesives; The performance requirements are also different; high and low temperature resistant hot melt adhesive is a kind of hot melt adhesive that can withstand high temperature and meet low temperature requirements at the same time. This article will give you a detailed introduction to the difference between high and low temperature resistant hot melt adhesives and ordinary hot melt adhesives, and the application fields of high and low temperature resistant hot melt adhesives;

The color and shape of the high and low temperature resistant hot melt adhesive is roughly the same as that of the ordinary hot melt adhesive. The color of the high and low temperature resistant hot melt adhesive depends on the difference of the hot melt adhesive composition and material. Common colors are light yellow, transparent, milky white, fog white, amber, black, etc.; shapes can be based on construction equipment: glue sticks, granules, flakes, short sticks, blocks, etc.; high and low temperature heat resistance Compared with ordinary hot-melt adhesives, the melted adhesive is more refreshing in appearance and color, with no impurities and odor, and is more environmentally friendly;

Compared with general hot melt adhesives, the application field of high and low temperature resistant hot melt adhesives is more detailed and professional. The material composition ratio of high and low temperature resistant hot melt adhesives is professionally adjusted, and the adhesiveness of the colloid is stronger and its performance is more stable; common Applications include household appliances, new energy vehicle wiring harnesses, food packaging, air filters, automotive filters, automotive interiors, industrial circuit boards, etc.;

In the application of hot melt adhesive for household refrigerators, ordinary hot melt adhesives may be brittle at low temperatures and soften at high temperatures; for the high temperature in summer and the extremely cold environment of refrigerators, it is necessary to ensure that the high temperature does not soften, but also To ensure that the low temperature is not brittle and does not lose viscosity. At this time, the high and low temperature resistant hot melt adhesive can better meet the process requirements than ordinary hot melt adhesives;

In industrial production: high and low temperature resistant hot melt adhesives are suitable for printed circuit board parts in the electronics industry, such as substrates, capacitors, electrical appliances, audio, optics, power supplies, chargers, electronic harness connectors, adapters and other control board parts Insulation, dustproof, shockproof, filling, fixing and connecting. It also has excellent adhesion to ABS, PVC, PC and other plastic items.

Air filter hot melt adhesive is used in the bonding and assembly of various air filters, HEPA filters in the medical field, air sterilizers, air purifiers and other air filter device frames (frame sticking, coating interval fold lines). For composite processing of aluminum, ABS, PP, PC, PE, PET, activated carbon, non-woven fabrics, metal, glass, paper and other materials.

High and low temperature resistant hot melt adhesive is also used in high-end bathroom shower room, steam room, sauna room, bathroom mirror and other glass and aluminum, stainless steel splicing and assembling a special hot melt adhesive developed for insulating glass, 100% solid content, moisture content Gas-reactive polyurethane hot-melt adhesive has good adhesion to difficult-to-stick materials such as aluminum alloy, stainless steel, glass, PC, ABS, and pretreated PP.

It can also be widely used for high and low temperature resistant hot melt adhesives for paper packaging. Paper packaging in various industries, large, medium and small cartons, paper color boxes, honeycomb panels, white cardboard, corrugated paper, laminated paper, UV film paper and other paper materials have strong adhesion. High and low temperature resistant hot melt adhesive products are non-irritating, strong adhesion, fast hardening speed, fast 1-3 seconds, bonding positioning, easy operation. It has good low temperature non-brittle characteristics and adhesion.

High and low temperature resistant hot melt adhesive can also be used in low-voltage injection molding of electronic cables, low-voltage injection molding of batteries, low-voltage injection molding of circuit control boards of automobiles and electric vehicles, wiring harness connectors, automotive sensors, induction coils, solar photovoltaic junction boxes, electronic module packaging, etc. At the same time, it is also suitable for the use of imported or domestic low-pressure injection molding line equipment, reaching the level of similar international products.
