What your process engineer actually checks

What your process engineer actually checks

Painted-quality exteriors, straight from the mold

770P is a high-flow, mineral-filled thermoplastic polyolefin (TPO): it fills large parts like bumper fascias (28 MFR), balances a 1,600 MPa flexural modulus with impact toughness, and is UV-stabilized and molded-in-color so parts skip painting. Every unit ships with molding guidance.

About this product

TPO 770P Black is a high-flow, mineral-filled thermoplastic polyolefin (TPO) engineered for large, molded-in-color automotive exteriors — UV-stabilized, with a strong stiffness-to-impact balance and painted-quality surface aesthetics straight from the tool. Based on the Hifax™ TRC 770P grade.

Why engineers choose TPO 770P

Automotive-grade polyolefin for large exterior parts, no paint step.

High flow (28 MFR)

Fills large, complex molds such as bumper fascias in one shot, reducing cycle time and short-shot risk.

Stiffness/toughness balance

A 1,600 MPa flexural modulus gives structural rigidity while impact resistance keeps exterior parts durable.

UV-stabilized, molded-in-color

Weatherable color built into the resin, eliminating the paint line for exterior parts.

Low density

Lower density (1.02 g/cm³) than engineering plastics offers lightweighting potential on large panels.

How we supply it

Genuine resin, ready to mold, with the parameters your process engineer needs.

Step 01
Sourced & lot-traced

Genuine Hifax TRC 770P TPO in black, packed in sealed 2 lb units and shipped from US stock. Minimum order 5 units.

Step 02
Mold ready

Polyolefins absorb little moisture, so drying is not typically required. Store sealed in a dry place before use.

Step 03
Molding parameters included

Melt 200–230°C (392–446°F), mold 40–80°C (104–176°F) for the best surface finish.

Typical applications

Large, weatherable, molded-in-color exterior parts.

Common questions

Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.

What is TPO 770P used for?
TPO 770P is designed for large, molded-in-color automotive exterior parts — bumper fascias, exterior trim, body panels, and RV or industrial vehicle exteriors. Its high flow, UV stability, and stiffness/impact balance make it a practical choice for weatherable exterior parts that skip the paint step.
What does molded-in-color mean for TPO 770P?
Molded-in-color means the color and UV stabilization are built into the resin, so finished parts come out of the tool with their final appearance and do not need painting. That removes a paint line and its cost while giving weatherable color on exterior parts.
Do I need to dry TPO 770P before molding?
Not usually. As a polyolefin, TPO 770P absorbs very little moisture, so drying is not typically required. Store the sealed units in a cool, dry place and keep them closed until use. A short dry only helps if the pellets have been exposed to humidity for a long time.
What melt and mold temperatures does TPO 770P need?
TPO 770P molds at a melt temperature of 200–230°C (392–446°F) with a mold temperature of 40–80°C (104–176°F). A warmer mold within that range improves the surface finish on visible exterior parts. These are starting points — a materials engineer can help tune them for your part.
Is TPO 770P weatherable for outdoor use?
Yes. TPO 770P is UV-stabilized specifically for long-term weatherability, which is why it is used for automotive exteriors that live outdoors. The stabilization helps the molded-in color and mechanical properties hold up under sun and weather exposure.
How is TPO 770P packaged and what is the minimum order?
TPO 770P ships in sealed 2 lb units, and the minimum order is 5 units (10 lbs total). Larger volumes and official purchase orders are welcome — contact us for volume pricing. Material ships from US stock, typically within 1–2 business days.
Will TPO 770P run on the APSX-PIM desktop molder?
Yes. TPO 770P is formulated for standard injection molding, including the APSX-PIM, though large production fascias need a larger press. On a desktop molder it is well suited to scale exterior parts and prototypes. Our team can confirm shot size and parameters for your mold.
