Additives for Polyurethane

Polyurethane Introduction

Polyurethane, abbreviated to PUR and PU is a polymer composed of organic units joined by urethane links. Polyurethane products often are simply called “urethanes”. Polyurethane is used in the manufacture of high-resilience foam seating, rigid foam insulation panels, microcellular foam seals, and gaskets, etc.

Polyurethane could be classified into polyurethane form plastic, polyurethane adhesive, polyurethane coating, polyurethane fiber, and polyurethane elastomer by applications.

 

Baoxu Additives for Polyurethane

Baoxu Chemical Supply Antioxidants, Colorants, flame-retardants, UV Stabilizers for Polyurethane.  We Simply Plastic Compounding. Color, Flame retardants, and Heat & UV resistance are 3 difficulties in polypropylene processing.

 

Antioxidant for Polyurethane

Polymer antioxidants can be added to improve the shelf life of the product or to improve its high-temperature stability. while adding a stability margin during thermal processing. Antioxidant BX AO 1010, BX AO 245, BX AO 168 is used a general purpose Antioxidant for Polyurethane plastics, BX AO 1135, BX AO 5057 as general antioxidant for polypropylene form as well as blend BX AO PUR67, PUR70, etc.

 

Pigment and Dyes for Polyurethane

Colorants give color to polymers, plastics, coatings, inks, and fiber. Every color we see in our daily life is related to colorants. For industry usage colorants, we offer organic pigments, solvent dyes, fluorescent pigments, and titanium dioxide. In the colorant portfolio, our products are analogs to BASF and other brands.

 

Flame Retardant for Polyurethane

Combustion could occur when a substance is heated to its flammable temperature in the presence of oxygen. Flame retardants are generally designed to provide a particular level of resistance to ignition or flame spread. This is achieved by suppressing oxygen availability, building up of char at the surface, inhibiting the combustion reaction within the flame area, or by other mechanics.

Halogen Flame Retardants for Polyurethane

BX FR DBDPE, antimony trioxide can be used as halogen flame retardant for polyurethane.

Halogen Free Flame Retardants for Polyurethane

For halogen-free flame retardants for polyurethane, BDP, MCA, and ADP can be used as non-flame retardants for polyurethane.

Lubricant for Polyurethane

Lubricants are a kind of additive used to improve the processing and appearance of polymers. The function of lubricants is to reduce friction, improve fluidity and mold release during resin or compound processing, and increase the surface smoothness of products. EBS, Montan Wax can be used as lubricant for Polyurethane.

 

Optical Brightener for Polyurethane

Optical brighteners are used to mask yellow or increase the whiteness of plastics, inks, coatings, paper, and fiber. OB and KSN can be used in Polyurethane as optical brighteners.

 

UV Stabilizer for Polyurethane

UV stabilizers contain two types of light stabilizers: Ultraviolet Light Absorbers (UVA) and Hindered-Amine Light Stabilizers (HALS), used individually or as blends. UVA filters harmful UV light and helps prevent color change and delamination of coatings, adhesives, and sealants. HALS trap free radicals once they are formed and are effective in retaining surface properties such as gloss and preventing cracking and chalking of paints. The combination of these two families is highly synergistic. BX UV 234, BX UV 312, BX UV 866, BX UV B75, BX UV 1, BX UV 292 can be used as uv additives for polyurethane products including PU form, PU adhesive, TPU or PU coatings.
