Haysite Reinforced Plastics

What Haysite Reinforced Plastics does

Haysite Reinforced Plastics, founded in 1954 and headquartered in Erie, Pennsylvania, is a privately held manufacturer specializing in the formulation and processing of thermoset composite materials. The company operates a 103,000 sq ft manufacturing facility with 1,400 sq ft of on-site testing laboratories and is a subsidiary member of the Isovolta Group, an international composite materials conglomerate. Its core technical capabilities span four manufacturing platforms: laminated sheet (offering over 25 grades), engineered molding compounds (BMC and SMC), custom compression molding, and pultruded sheets and profiles, supported by proprietary formulations such as Dura-Core H1000 and branded lines including Thermalate and Heatmeiser.

The company serves six primary market verticals: transit (with products meeting NYCTA specifications 64 and 65 for flame, smoke, and toxicity), electrical insulation (GPO-1, 2, and 3 grades), corrosion resistance (for laboratory fume hoods and water/wastewater treatment), platen insulation, structural applications, and medical and electronics. Its products compete on weight reduction versus metal and wood, dielectric strength, FST compliance, chemical resistance, and compressive performance.

Haysite operates a direct sales model through phone, fax, and website contact forms, selling to industrial manufacturers and transit authorities without disclosed pricing or a distributor network. Revenue is generated entirely from hardware sales of composite materials and custom-molded parts; no pricing tiers, no subscription or recurring software revenue, and no customer logos are publicly disclosed. The company's value proposition centers on vertical integration (material formulation through finished part molding) and UL-listed, specification-compliant products in safety-critical applications.

Core offering

Haysite Reinforced Plastics formulates and manufactures thermoset composite materials and fiberglass reinforced plastic (FRP) products, including laminated sheet, custom compression molded parts, pultruded sheets and profiles, and engineered molding compounds (BMC and SMC). The company serves industrial customers in transit, electrical insulation, corrosion resistance, platen insulation, structural, medical and electronics markets, with both stock and custom configurations produced at its Erie, PA facility.

Product overview

Haysite Reinforced Plastics is a worldwide leader in the formulation and processing of thermoset composite materials, offering one of the broadest product lines in the fiberglass reinforced plastics industry since 1954. The company operates a 103,000 sq ft facility in Erie, PA, with comprehensive in-house capabilities spanning material formulation, compression molding (SMC and BMC), and pultrusion. The product portfolio centers on four core manufacturing capabilities: Laminated Sheet (in over 25 grades), Compounds/Bulk Molding Compounds, Custom Compression Molding, and Pultruded Products (sheets and profiles). These feed into five key market verticals: Transit Products (including Dura-Core 1000 flooring and H1000 material meeting NYCTA specs), Electrical Insulation (GPO grades), Corrosion Resistance (for laboratories and water treatment), Platen/Mold Insulation (Thermalate and Heatmeiser brands), and Structural applications. The company maintains in-house testing facilities and UL listing for many materials.
