Plastic Parts for Harsh Environments: UV, Chemicals, Impact, and More

When it comes to engineering solutions for rugged conditions, one size doesn’t fit all, especially in the world of plastic components. At Gemini Plastics, we understand the demands of environments that push materials to their limits. Whether it’s relentless UV exposure, corrosive chemicals, high-impact forces, or extreme temperatures, our custom plastic parts are engineered to endure, perform, and protect.

The Challenge of Harsh Environments

Industries like agriculture, chemical processing, marine, transportation, and medical equipment operate in conditions where traditional materials often fail. Moisture, salt, abrasion, UV rays, and harsh solvents can quickly degrade unprotected parts, leading to costly downtime and replacements. Plastic, however, has evolved. With today’s advanced resins and molding technologies, engineered plastics can outperform metals and other traditional materials when designed correctly. Gemini Plastics leverages over 50 years of plastics 00expertise to craft custom plastic solutions tailored to these demanding environments.

UV-Resistant Plastics: Protection from the Sun

Outdoor applications expose components to prolonged ultraviolet (UV) radiation, which can cause brittleness, discoloration, and loss of mechanical integrity. We combat this with:

• UV-stabilized materials such as polycarbonate, ASA, and UV-rated HDPE.

• Co-extruded layers for added UV protection in multilayer parts.

• Additives and coatings that extend the part’s lifespan without sacrificing appearance.

From agricultural equipment covers to marine housings, our UV-resistant plastics maintain their strength and color over time.

Chemical Resistance: Shielding Against Corrosive Substances

Exposure to acids, solvents, oils, and disinfectants is common in many industries. That’s why Gemini Plastics offers Chemical-resistant materials like polypropylene, PVDF, PTFE, and certain grades of polyethylene and nylon.

Impact Resistance: Built to Withstand Force

In environments prone to shock, vibration, or heavy use, brittle materials simply won’t do. Gemini Plastics crafts impact-resistant parts using tough polymers like ABS, HDPE, and impact-modified acrylics.

Whether it’s a transportation panel, construction equipment shield, or warehouse bumper guard, we ensure your parts can take a beating and keep going.

Beyond the Big Three: Other Environmental Stressors

Temperature Extremes

We select materials rated for sub-zero or high-heat environments, ensuring dimensional stability and safety.

Moisture and Water Exposure

Hydrophobic plastics like PTFE and sealed part geometries protect against water intrusion and swelling.

Abrasion and Wear

We engineer wear-resistant surfaces for parts exposed to friction or gritty media.
