4Plastic, a specialist plastic technology company focused on solutions for modern collision repair, has launched its filler-free plastic repair process and product line in N.A. The goal is to give fleets and shops a repair-first option for restoring damaged plastic components—reducing replacement costs, waste, and downtime tied to cosmetic rebuilds.

“4Plastic’s patented, filler-free technology restores polypropylene parts through precisely controlled heat, targeted push reshaping, and seamless fusion welding using an automotive-grade material engineered to bond perfectly with the original substrate,” said Michael LoPrete, managing director of 4Plastic.

According to 4Plastic, the technology has been deployed at scale for four years through an exclusive agreement with The Boyd Group, which has about 1,300 locations across the United States and Canada. There, it was refined in high-volume repair environments.

The approach originated in Australia and has been used for decades across Australia, New Zealand, and Europe before its North American rollout. With exclusivity now concluded, the full product and tool range is being introduced to the broader market, with distribution in the U.S. and Canada through SEM Products.

For fleet maintenance operations, the value is in reducing unnecessary part replacement. Plastic components on trucks and trailers—such as bumpers, lamp housings, mirror backs, fairings, and interior panels—are often replaced because traditional repairs rely on fillers that crack, separate, or fail under vibration and temperature changes. A fusion-based repair can improve durability, limit rework, and shorten cycle time compared to ordering and installing new parts.

Key benefits include:

Elimination of filler materials & applications
Improved durability and long-term performance
Reduced rework, comebacks, and warranty exposure
Lower material costs and reduced waste
Support for OEM-aligned repair & consumer safety outcomes

4Plastic also says it is expanding its product ecosystem with tools, equipment, and training aimed at producing consistent, repeatable results across shops.

LoPrete said that 4Plastic’s plastic repair system enables the industry to move beyond cosmetic fixes toward true structural restoration.

“This launch marks a meaningful shift in the market, setting a new expectation for quality, repeatability, and sustainability in plastic repair,” he concluded.
