Wholesale NEOPRENE ADHESIVE price china is a kind of adhesive with good adhesion performance to various substances and large initial adhesion. At the same time, the elasticity of rubber has an excellent cushioning effect on the volume shrinkage of materials with different expansion coefficients, impact and vibration. Therefore, the adhesive can be prepared.

1. Wholesale NEOPRENE ADHESIVE price china

Wholesale NEOPRENE ADHESIVE price china is an additive polymer of 2-chloro-1,3-butadiene. The adhesive made of neoprene rubber is called neoprene adhesive for short. Because of its high crystallinity, large polarity and excellent adhesion, it is the most widely used rubber adhesive, accounting for more than 70% of the total amount of synthetic rubber adhesive.

(1) Varieties of Wholesale NEOPRENE ADHESIVE price china

① The contact adhesive is generally composed of high crystallinity AC type or AD type neoprene polymer and alkyl substituted phenolic resin, and zinc oxide, magnesium oxide, antioxidant and other additives are added. The solution is made of aliphatic hydrocarbon, aromatic hydrocarbon, ketone or ester solvent.

② AF adhesive The AF type polymer of neoprene rubber contains hydroxyl. Because it contains hydroxyl, the temperature of rubber refining must be controlled below 25 ℃ to prevent reaction with additives and magnesium oxide. In addition, if only aromatic solvent is used, the solution will lead to wire drawing, so a small amount of water must be added in coordination.

③ HC adhesive Neoprene HC polymer has high crystallinity. If the polymer heated to 70 ℃ is cooled and kept at room temperature, its hardness will increase rapidly in a few minutes, while the complete crystallization of other types of neoprene rubber will take at least two hours. HC polymer hardly softens below 50 ℃, but rapidly softens when it exceeds 50 ℃, and its viscosity is low when it melts at high temperature. These characteristics indicate that it is particularly suitable for making heat sealing adhesives.

(2) The advantages of Wholesale NEOPRENE ADHESIVE price china and its application have the following advantages:

① Wholesale NEOPRENE ADHESIVE price china has outstanding flexibility;

② Good oil resistance and chemical resistance, non-toxic or low toxic, nonflammable;

③ Good anti-aging performance;

④ Because it contains polar groups, it has high adhesive strength and wide application range;

⑤ Generally, Wholesale NEOPRENE ADHESIVE price china can be made into one component adhesive without vulcanization, which is convenient to use.

Wholesale NEOPRENE ADHESIVE price china has excellent flame resistance, ozone resistance, aging resistance, oil resistance, water resistance, solvent resistance and chemical resistance, so it is widely used in construction, shoemaking, electronics, textiles, automobiles, shipbuilding, etc.

Wholesale NEOPRENE ADHESIVE price china shall be applied on a clean, dust-free, dry and oil free site at a temperature of 1535 ℃. When the relative humidity is less than 80%, pressurize appropriately.
