Building & Industry

Materials designed for building & industry applications

Tough as nails or flexible and subtle.  We love to formulate and our portfolio shows it!  Extrusion applications include seals, gaskets, profiles, tubes, and hoses.  Molding applications move from pliable and precise parts like seals, grips, gaskets and grommets to substantial and rigid parts such as battery jars.  Sheet extrusion materials flow smooth as silk while our color concentrates easily blend during processing, providing a fantastic variety of vivid colors.

The brand names DUROVIN, EVOPRENE, MEXIFLEX, PROVIN, SYLVIN, and VINASTAB are trademarks of Alphagary/Mexichem.

Typical Applications

Our materials are used in a vast array of applications - here are some examples.  We have numerous off-the-shelf options and often custom-formulate a material to fit customer specifications.  By understanding the necessary performance criteria, we can recommend suitable candidates and work side-by-side throughout the approval process.

Put our experience to work.

Consistency with every blend

We understand how important it is for materials to perform consistently and reliably. That’s why we have adopted fixed practices that govern formulation integrity, process control and data acquisition. Customers trust us for this assurance so they can focus on creating dependable and functional products that enhance our lives every day.   so critical to our health and wellbeing.

Regulatory Expertise

We have full-time regulatory expertise to help navigate everchanging regulations. And we’re transparent with reporting information. In our Safety Data Sheets, made for each product, we report Substances of Very High Concern, phthalate content, and REACH, RoHS, and Prop 65 information along with the necessary safety precautions typically found on a safety data sheets. Our customers find this information very helpful as they answer regulations and apply for third-party approval.

Dedicated R&D Team

With fully appointed laboratory resources and decades of hands-on experience, we work closely with customers to choose the right candidates off-the-shelf or re-engineer based on performance requirements.  Working with a variety of polymers means we have a broad range of solutions to choose from.
