PVB Polyvinyl Butyral Resin

PVB Polyvinyl butyral
Product description
Polyvinyl butyral a kind of high-molecular polymer through the condensation reaction, PVA and butanal as raw material, hydrochloric acid as catalysis. It's chemical name is Polyvinyl Butyral Resin, short for PVB. It not only has high transparency, good light resistance, cold resistance, water resistance, film properties and impact resistance performance, but also has a good bonding performance for Glass, metal, wood, ceramics, leather, fiber, etc. It has been widely applied in the industrial sector, such as the film in the middle of safety glass, Porcelain stained paper, Metal protection primer, tipping paper, Aluminum foil paper, Insulating paint, Fiber treating agent, printing ink, dye, man-made sponge, etc. The product is non-toxic, tasteless, and adhesive force, without impurities, high transparency and so on.

Applicable fields

1, Transfer printing
PVB (aleurone) is the best bonding agent in transfer printing paper raw material ink, because of it is non-toxic, tasteless, high transparency, good gloss and strong tensile force, Prevent sun exposure, aging resistance is strong, at the same time, It has a good solubility with alcohol and dye, Uniform degree of polymerization, ect. It has become the indispensable raw materials in the transfer printing paper production process. Before the printing products, the user according to the concentration of the ink, add methanol, isobutanol, paste(PVB methanol solution), ect. To modulate suitable printing ink.

2, Copper-clad plate
PVB and phenolic resin mixed use can produce the best copper foil adhesive to make paper base copper-clad plate.

3, Adhesive
PVA has a strong adhesive property, so it can be made into all kind of adhesive.

A. Bonding glass: Because PVB high adhesive force, proper elasticity and plasticity, so it can be used for bonding glass.

B. Bonding metal: Mixed PVB and phenolic resin, it will made into different type of acetal phenolic glue, it can be used in all kinds of metal bonding.

C. Bonding enameled wire coil, coating the PVB solution on the coil, after heating, the coil will be adhesive,

D. Heat sealing adhesive: PVB mixed with natural resin, synthetic resin and plasticizer, can be used as heat sealing property adhesive.

E. Transfer trademark bonding agent: PVB can be used as ceramic transfer trademark adhesive, the finished ceramic's color is bright and feel smooth. It has been widely used as ceramic stained paper resin. In addition, it also can be used for textile transfer trademark.

F. Bonding film: PVB mixed with other synthetic resin, synthetic rubber and plasticizer, can be used as cloth and cloth or other material heating adhesive.

G. Pressure sensitive adhesive: It can be used as the adhesive materials of cellophane tape, polyethylene adhesive tape and other pressure sensitive type adhesive tape

H. Feather adhesive: Used for feather bonding, which are widely used in badminton production.

I. Other adhesive: Can be used as the material of non-woven fabrics adhesive, electrostatic flocking adhesive and leather adhesive.

4, ceramic (enamel) stained paper, Make the PVB become 12%-14% ethanol solution, then make the solution become the film, it can instead of ceramic (enamel) stained paper after printing, the finished ceramic's color is bright and feel smooth. The ceramic stained paper with decorative pattern is wet, adhere to the surface of the ceramic and textiles and then tore away. Design is printed on the surface.
