Common Plastic Resins

Below is a quick reference for some of the most common plastic resin materials and some of their common applications!

Nylon (PA 6, PA 6/6)

Nylon, a synthetic thermoplastic, is a material we commonly use for fastening and connecting applications. Nylon’s downside is that it has a relatively low impact strength, which is why it’s vital to combine with other materials (such as glass fibers) to improve its strength. It’s also important to understand the complexities of material flow and injection point(s) with nylon.

Recommended Wall Thickness: 0.030″ – 0.115″

Common Applications
  • Barbed Fluid Routing Connectors
  • Brake Line Clips
  • HVAC Line Line Clips
  • Jounce Bumper Assemblies

Low-Density Polyethylene (LDPE)

Low-density polyethylene is a low-cost thermoplastic polymer material used in a variety of applications.  Echo Engineering specializes in catalog and custom LDPE products used mainly by automotive and fluid power manufacturers for shipping protection applications.

Recommended Wall Thickness: 0.030″ – 0.200″

Common Applications
  • A/C Line Shipping Caps
  • Hydraulic port plugs
  • Engine and Transmission inlet/outlet port plugs
  • General purpose shipping caps/plugs

Thermylene®

Thermylene®is a specialty chemically coupled glass reinforced polypropylene (PP) which helps it resist distortion under load. Because of it’s glass-reinforced properties, material flow will be crucial towards molding a successful product.

COMMON APPLICATIONS
  • Suspension Components
KEY ADVANTAGES
  • Superior knit line strength
  • Excellent chemical resistance
  • Enhanced tensile strength

THERMOPLASTIC POLYURETHANE (TPU)

TPU is a material commonly known as a bridge between rubbers and plastics.  Even though it is plastic, it can be extremely flexible and durable.  Because of this, TPU has a variety of different automotive applications.

COMMON APPLICATIONS
  • Suspension Components
  • Driveshaft Boots
KEY ADVANTAGES
  • High tensile strength
  • Excellent wear, tear, and abrasion resistance
  • Increased resistance against oils, greases, oxygen, and ozone
