Base Polymers Used by Plastic Compounding Suppliers

Specialty compounding is a manufacturing process that mixes creativity and science to create beautiful and practical plastic parts. We use modern technology to enhance base resins with reinforcements and additives. The end product is a unique material that meets strict aesthetic and performance criteria.

We use a wide range of different base polymers to meet the demands of our clients. Some of the most common base polymers we use include:

Polypropylene (PP): this polymer offers users a good balance of properties and low costs when compared to many other thermoplastics. The material is efficiently processed while maintaining strong chemical resistance.

Advantages

  • Resists chemicals
  • Heat resistant
  • Lightweight

Limitations

  • Weak impact resistance in cold temperatures
  • Difficult to paint and bond

Acetals (POM): this is a strong, rigid and creep resistant polymer. They boast low coefficients of friction. They are easily able to perform in high-temperature environments. Strong bases barely affect parts.

Advantages

  • Creep and fatigue resistant
  • Solvent resistant
  • Highly Resilient

Limitations

  • Anisotropic shrinkage
  • High specific gravity

Polycarbonate (PC): this material maintains excellent impact strength, good dimensional stability, and high heat resistance. It is known as one of the first thermoplastics to offer these characteristics.

Advantages

  • Toughness
  • Creep resistant
  • Dimensional stability

Limitations

  • Weak chemical resistance
  • Low fatigue endurance
