Additives for Polyester PET

Introduction of Polyester PET

PET is an abbreviation of Polyethylene terephthalate (sometimes written poly(ethylene terephthalate)), which is the most common thermoplastic polymer resin of the polyester family.

The main application includes polyester fibers for clothing, containers for liquids and foods, thermoforming for manufacturing, and in combination with glass fiber for engineering resins.


Baoxu Additives for Polyester PET

Baoxu Chemical Supply Antioxidants, Colorants, flame-retardants, Heat Stabilizers, Impact Modifiers, Lubricants, Nucleating Agents, OBAs, UV Stabilizers for Polyester PET plastics.  We Simply Plastic Compounding.


Antioxidant for Polyester PET

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 1076, BX AO 168 is used a general purpose Antioxidant for PET plastics, BX AO 626 together with BX AO 1010 can be used for a high-performance Antioxidant for PET.


Flame Retardant for Polyester PET

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.

For halogen-free flame retardant for PET, aluminum diethyl phosphinate ADP BX FR ADP is recommended.

Brominated flame retardant, BX FR 245, BX FR DBDPE, and antimony trioxide BX FR Sb2O3 are used together as halogen flame retardants for PET.


Impact Modifiers for Polyester PET

Impact Modifiers are substances that increase the durability of molded or extruded plastics, especially those that need to be constantly subjected to impact forces like cold weather. They are added to compounded materials to provide performance features. They provide strength and break resistance to the product for which they are added. They also provide rigidity to the product to prevent it from wrapping or sagging during everyday use. POE-GMA and E-MA-GMA are used as Compatibilizers and Impact modifiers for PBT. Arkema AX8900 is frequently used in PET.

Lubricant for Polyester PET

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.  Erucamide, Oleamide can be used as lubricant for PET.


Nucleating Agent for Polyester PET

Nucleating agents which also known as clarifying agents (clarifiers), improve the crystallization of semi-crystalline polymers. BX NA 101 can be used for PET..


Optical Brightener for Polyester PET

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 PET as optical brighteners.


Pigment and Dyes for Polyester PET

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.


UV Stabilizer for Polyester PET

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. UV absorber BX UV 329. BX UV 3638, can be used in PET as UV Stabilizer.
