Chemical additives are essential raw materials in the plastics industry. The plastics industry relies heavily on masterbatches and compounding processes to achieve desired properties. From automotive parts and household goods to industrial packaging, manufacturers need additives to enhance the strength, lifespan, safety, and aesthetics of plastics.
Essential Plastic Additives
Plastics are susceptible to the effects of heat and light. During extrusion or injection molding, the material becomes extremely hot. Without protective measures, plastics may yellow or lose mechanical strength.
Antioxidants are the primary stabilizers. They prevent thermal degradation in the molten state of the plastic.
After the product is manufactured and exposed to sunlight, Light stabilizers and UV absorbers come into play. They absorb harmful radiation or neutralize free radicals generated by UV rays, preventing the plastic from chalking, becoming brittle, or discoloring.
Flame retardant additives are quite important for electronic and construction plastics, reducing fire spread and complying with safety regulations. The product line covers high-efficiency halogenated and environmentally friendly halogen-free series: DBDPE, BTPE BT-93, BDDP, and High Purity aluminum hydroxide, High Purity Magnesium Hydroxide, FR-245, MCA, etc.
As DBDPO, TBBA, and Antimony Trioxide have all faced varying degrees of restrictions or even bans due to environmental concerns, we previously sold these fire retardants. However, many customers are now requesting that we switch to more eco-friendly flame retardants for them.

Surface and Performance
To get a better touching feel, soft-touch PU powder can be added to composite materials in handles, dashboards, or toys to create a leather-like texture; or PMMA beads can be used to enhance scratch resistance.
To keep products clean, anti-static agents are essential for packaging electronic products or dustproof goods. They reduce static electricity, prevent dust from adhering to the product, and avoid electrostatic shocks.
Slip agents migrate to the surface of films (such as plastic bags), reducing the coefficient of friction. This makes the film less sticky and easier to open.
Making Plastics Flexible and Flexible, Seamless Molding
To improve production efficiency, nucleating agents help plastics cool and solidify into the desired shape faster.
Plasticizers are specially used in PVC to give it flexibility.
Adhesion promoters are very useful when plastics require secondary coating or bonding, ensuring strong adhesion.
Polyethylene oxide (PEO) can be used as a processing aid or release agent in some applications.
Mixed Blends
To ensure all these components are mixed uniformly, a liquid or solid carrier must first be used.
Dispersants and wetting agents help solid additives mix with molten plastic and prevent clumping.
Leveling agents are more common in liquid plastic coatings, but solid form polyethylene wax (PE Wax) is often used as a lubricant or dispersant in masterbatches to improve flowability and yield.
Dimeric acid is a key raw material in the manufacture of polyamide hot melt adhesives, which are used to bond plastics.

FAQ
Q1 All these above are all plastic additives you can supply?
No. We can supply almost most of industrial grade chemical additives which will be used in various plastics, inks, coatings, textiles and other uses.
So please contact us to get the complete plastic additive product list.

Q2 How do I stop my plastic parts from yellowing?
You must use a combination of Antioxidant and UV Stabilizers & UV Absorbers.
Q3 What if I need a matte look on my plastic?
Our Matting Agent and Soft Touching PU Powder are perfect for reducing shine.
Q4 How do I help the color spread in the plastic?
Use our Dispersants, Leveling Agents, and Adhesion Promoter to ensure the color and thickness are even everywhere.
Q5 How does a Nucleating Agent make plastic clearer?
It works by creating many tiny crystals in the plastic as it cools. These small crystals allow light to pass through rather than scattering it, which improves clarity and reduces haze.
Q6 Is Dimer acid or Nucleating Agent used here?
Dimer acid helps in making the ink resin, while Nucleating Agent is more common in the plastic substrate the ink is printed on.
