Solvent Base Resin
- Solvent base resin is synthesis from polyester polyols, chain extending agents and isocyanate in a solvent polymerization. Based on product features, it can be used with different polymeric polyol and suitable additives. Such resins have various excellent functionality, for example, wear-resistant, waterproof, breathable, anti-static, anti-bacterial mold, wear comfortable, and other characteristics.
【Moisture Permeable】
● Application: All kinds of outdoor equipment and garment coating.
【Low Moisture Permeable】
● Application: Adhesive for all kinds of specialty paper, waterproof layer for garment, and leather / furniture adhesive.
PU Foam Resin
- Two-liquid-type foam PU, is formed by the synthetic reaction of isocyanate (with NCO on tail) and polyol (with –NH2 on tail). According to different requirement, one could change the percentage of short diol or diamine, catalyst, anti-tacky agent, foaming control agent, or water, etc. The process is under catalyst-condition, causing rapid reaction time. The reaction and foam-growing procedure are usually in 1-30 min, and the final properties of foam would be obtain in 1-2 days.
● Application: PU foam wheel, seat, handrails, and outsole, the insert, insole for all kinds of footwear.
● Advantage: Good flexibility, good abrasion resistance, hydrolysis resistance, good compression resilience, light weight.
Polyester Polyol
- Polyester polyol is foamed by condensation of dicarboxy acid and dibasic alcohol. Alcohol would not only be used for long ester chain, but also be contained in the tail group (-OH). Therefore, alcohol should be excess 5/20% for condensation reaction. And the ration of polyacid and polyol should be determined by the desired final molecular weight or equivalent. Polyester polyols contain many ester group in structure, which leads to better product properties than polyether polyol, such as rigidity, thermal stability, permeability, oil resistance and adhesion.
● Application: PU resin, adhesive, foam, elastomer.
● Depends on the choice and the application of Polyols, when choosing various Polyols as PU formula, one should manipulate the structure of Polyols, in order to concern the reaction condition and the usage of catalyst and additive, which would determine the morphology and properties of formed PU polymer.
Reactive PUR Hot Melt Adhesives
- The isocyanate pre-polymer is formed by the addition polymerization reaction of isocyanate and polyol compound, it does not contain organic solvents and has no pollution problems such as VOCs. It’s eco-friendly hot melt adhesive with 100% solid content which performances of adhesion fastness and washing fastness are stunning
PU Prepolymer / PU Elastomer
- Polyurethane elastomer is oligomer molecular chain with reactive isocyanate (-NCO) functional group added to both ends; at the time of infusion, mixing with double amines (-NH2), double alcohol (-OH) and other molecules to produce a high molecular weight polyurethane. Through the use of infusion devices or molds, perfusion can be mass-produced goods, such as industrial rollers, pulleys, roller stakes, PU runway, roofing, caulking construction.
The pre-polymer / elastomer developed by Shuang Bang has the performance between rubber and plastics. According to the recipe design, the products have high resilience, shock absorption, abrasion resistance, oil resistance, tear resistance, chemical corrosion and resistance to radiation and other properties. Customers can adjust formula according to their needs to make a variety of products.
● Application: Automobile industry, building material, shoe material, synthetic leather, medical equipment, sports gear, etc.
● Advantage: A great diversity of products, which covers most of the market demand. Customers can choose the prepolymer according to their needs r processing method or choose a set combination.
