Three synthetic latex common and characteristic Compared with natural latex, the commonality of synthetic latex lies in its excellent storage stability, mechanical stability, chemical stability and freeze-thaw stability during storage and application. The characteristics of different kinds of synthetic latex are as follows: Styrene-butadiene latex Butadiene series latex is a copolymer latex synthesized mainly by butadiene and styrene monomer. Butadiene gives the adhesive and resilience of latex, and styrene makes the polymer film have certain plasticity and stiffness. The difference in the ratio of the two can change the film forming temperature and glass transition temperature. The introduction of unsaturated carboxylic acid monomer enhanced the stability and adhesion of latex. Its advantages are a wide range of applications, low production costs; The disadvantage is poor resistance to chemicals and solvents. Butadiene-acrylonitrile latex Butadiene series latex is a copolymer latex synthesized mainly by butadiene and acrylonitrile monomer, and has good adhesion, oil resistance, chemical resistance and wear resistance. After the introduction of unsaturated carboxylic acid, the stability and adhesiveness of the product are further strengthened. These characteristics lay a good foundation for the use of this kind of products in grease impregnated products and wear-resistant parts. Its disadvantages are low temperature resistance and ozone resistance is poor, slightly lower elasticity. Nitrile gloves have good tear resistance, puncture resistance, grease protection and basic chemical protection, and have high protection safety and more thoughtful protection for users. Neoprene latex Because of the polar chlorine group, the latex has good adhesion, high film strength, oil resistance, flame resistance, solvent resistance, heat resistance, ozone aging resistance and other properties; Disadvantages are cold resistance, poor insulation, storage stability is not as good as the first two.

 Liquid end hydroxyl polybutadiene rubber (HTPB) is a liquid rubber with hydroxyl functional group at the end of the molecular chain of polybutadiene, which is colorless or light yellow transparent liquid at room temperature. HTPB and chain extender, polyisocyanate cross-linking agent in the reaction at room temperature or high temperature can generate three-dimensional network structure of the solidified material, the solidified material has excellent mechanical properties, good transparency, especially has excellent hydrolysis resistance, acid and alkali resistance, wear resistance, low temperature resistance and excellent electrical insulation, good adhesion to non-polar and low polar materials, excellent air tightness. The moisture transmittance is very low. HTPB has a wide range of applications. For a long time, it is mainly used in the manufacture of adhesives for solid propellants. In recent years, it has been gradually promoted for the production of civil cast-type polyurethane elasteers, RIM polyurethane products and CASE polyurethane elastic materials. Due to the excellent electrical properties of HTPB, water resistance, corrosion resistance and dimensional stability, it is also used for the production of complex shape insulating materials by the casting method. The main application fields of HTPB include pouring tires, rubber and plastic floor, plastic runway and complex shaped rubber products, shoe materials, special foam plastics, special coatings, adhesives, potting materials, electrical insulating packaging materials, waterproof and anti-corrosion materials, underwater sealing materials, wear-resistant transport belt and other rubber modification and epoxy resin modification and other uses.

The commonly used resins for waterborne wood paint are polyurethane and acrylic acid. Waterborne polyurethane resin is a wear-resistant resin commonly used in waterborne wood paint, which can form a hard, wear-resistant coating to provide good protection for wood.The commonly used resins for waterborne wood paint are polyurethane and acrylic acid. Waterborne polyurethane resin is a wear-resistant resin commonly used in waterborne wood paint, which can form a hard, wear-resistant coating to provide good protection for wood.Another common water-based wood paint resin is acrylic. It has good weather resistance, wear resistance and chemical resistance to form a strong and durable coating. The drying time of acrylic resin is shorter, the transparency is higher, and the natural color of wood can be maintained. First, waterborne wood paint self-extinction polyurethane resin Application fields Waterborne wood varnish varnish Waterborne wood paint solid color paint Wood surface treatment Product feature Good scratch resistance (such as scratch repair) Good color rendering Feel smooth or strong velvet Environmental protection Good adhesion to oil bottom Low gloss (near 0 degree light) Two, water-based wood paint self-extinction acrylic resin Application fields Waterborne wood paint full matte solid color paint (substitute matte powder dosage) Wood surface treatment Product feature High efficiency extinction Scratch resistance It does not absorb water or oil Environmental protection Rheology can be good High transparency Anti-tack Good stain resistance Self-extinction acrylic resin Self-extinction acrylic resin is a special process matte acrylic dispersion, with very good extinction effect and very good high temperature resistance. Water based polyurethane resin and water based acrylic resin have their own advantages in waterborne wood paint. Polyurethane resins offer increased wear and chemical resistance for applications that require greater protection. Acrylic resin has a faster drying time and good transparency, suitable for retaining the natural beauty of wood. When selecting water-based wood paint resin, it is necessary to choose according to the specific needs and application scenarios, and you can also directly contact Sinograce Chemical technical engineers for recommendation.

The difference between nitrile rubber and nitrile latex Different raw materials Carboxyl nitrile latex: butadiene, acrylonitrile and methacrylic acid Carboxyl nitrile butadiene latex (XNBRL) is a terpolymer of butadiene, acrylonitrile and acrylic acid or methacrylic acid, and is a modified variety of nitrile butadiene latex. Due to the introduction of carboxyl group, while containing C=C double bonds, sulfur vulcanization, peroxide vulcanization and other ways, so as to obtain a variety of excellent properties, and better than ordinary nitrile latex. Its products have excellent oil resistance, chemical resistance and mechanical properties, widely used in a variety of rubber and non-rubber products. The introduction of carboxyl group enhances the polarity and stability of XNBRL, improves the hardness and strength of XNBRL film, and XNBRL does not contain protein, does not cause human allergy, and is preferred for the manufacture of oil-resistant gloves and medical gloves. Nitrile rubber: butadiene and acrylonitrile Nitrile rubber is made of butadiene and acrylonitrile by emulsion polymerization.  Nitrile rubber is mainly produced by low temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance and strong adhesion. Its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance, and slightly lower elasticity. Different shape Nitrile rubber is in the form of blocks. Carboxyl nitrile latex is a milky liquid Different uses Nitrile rubber: Nitrile rubber is mainly downstream for foam products, rubber hose tape, seals and other fields. Carboxyl nitrile butadiene latex: The main downstream of carboxyl nitrile butadiene latex is labor protection gloves or disposable gloves. Price is different The price gap between the two is relatively large
