Product Information

Hot Melt Pressure Sensitive Adhesive (HMPSA) is a solvent-free, non-polluting pressure sensitive adhesive that is coated under molten conditions and has pressure sensitive adhesive properties after cooling. Thermoplastic rubber is its main material, but also need to add tackifying resin, plasticizer and a small number of other components. At higher temperatures (160-200 ℃) melt mixing made. It is coated in the molten state, applying light finger pressure can be quickly bonded, and at the same time easy to peel, not contaminate the surface of the object to be adhered to. Now has been widely used.
Petroleum resins are polymers of unsaturated hydrocarbon fractions of petroleum cracking by-products, which can be divided into aliphatic (C5 fraction), aromatic (C9 fraction), alicyclic and their modified resins, such as hydrogenated petroleum resins and other types. Aliphatic petroleum resins have a similar structure with natural rubber, have better compatibility with SIS, their softening point is generally 65-100 ℃, high melt viscosity, low price. Aromatic petroleum resin is vinyl toluene, styrene and indene polymers, no polar groups, softening point of 80-160 ℃. C5 petroleum resin with its excellent performance, safety, environmental protection and other aspects of the advantages, in recent years favored, as a low relative molecular mass of thermoplastic resins, with the condensation, viscosity and improve the viscosity of the performance, can be used as SBS hot-melt pressure-sensitive adhesive formulations of the blotting agent, play a role in improving the initial viscosity of the colloid, to improve the role of colloid wettability, and so on.

C5 Petroleum Resin for hot melt pressure sensitive adhesive
This product is suitable as a tackifying resin for hot-melt adhesives (e.g., fast packaging adhesives, bookbinding adhesives, woodworking adhesives, various glue sticks, etc.). They have good compatibility with SIS, SBS, EVA, natural rubber and all kinds of synthetic rubber, etc., and have different degrees of improvement on various properties of hot melt adhesives.

Company Information

Our company's main export products include

(1)  Super Absorbent Polymer

There are two types of industrialized Super Absorbent Polymers: one is hydrophilic polymers attached to starch or cellulose skeleton, such as acrylonitrile grafting polymerization and then hydrolysis of corn starch; the second type is synthetic cross-linked sodium polyacrylate. The former type has high water absorption, low raw material cost, and microbial degradation characteristics. The latter water absorption is low, high cost of raw materials, and not easy to be microbial degradation and corruption, both have been industrialized production.

(2) Polyacrylamide Product

Polyacrylamide (PAM) is a linear polymer with the chemical formula (C3H5NO)n. It is a hard, glassy solid at room temperature, with products such as glue, latex and white powder, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, and the aqueous solution is a uniform transparent liquid. The viscosity of the solution will decrease after long-term storage due to the slow degradation of the polymer, especially when the storage and transportation conditions are poor. Polyacrylamide is widely used as lubricant, suspending agent, clay stabilizer, oil repellent, water loss reduction agent and thickening agent in drilling, acidizing, fracturing, water plugging, well cementing, and secondary and tertiary oil recovery.
