What Polytek Development does

Polytek Development Corp. is a Pennsylvania-incorporated, PE-backed specialty polymer manufacturer founded in 1984 and headquartered at 55 Hilton St, Easton, PA. The company formulates and produces room-temperature-curing (RTV) specialty polymers — including platinum-cured and tin-cured silicone rubbers, polyurethane rubbers, plastics, foams and adhesives, epoxy systems, and latex — for mold making, casting, and coating applications. Its product portfolio is organized around branded lines (PlatSil, TinSil, EasyFlo, Poly-Optic, PT Flex, Polygel, PolyPoxy, Pol-Ease, FormRub, CPD) covering Shore hardness ranges from A10 to D85, and includes specialty certifications such as FDA 21 CFR 177.2600 food contact compliance and skin-safe certifications (FHSA, LHAMA, ASTM D4236) for theatrical, medical, and culinary applications. Under Arsenal Capital Partners' ownership, Polytek has executed at least nine acquisitions since 2017 (including Specialty Resin & Chemical, Endurance Technologies, Promise Epoxy, Stone Coat Countertops, Pro Marine Supplies, Environmental Technology, BCC Products, California Medical Innovations, and Raw Material Suppliers) to broaden its chemistry, channel, and end-market footprint.

The company serves a horizontally-segmented customer base spanning engineers and manufacturers in precast concrete and composites, theatrical and special-effects professionals, medical modeling and simulation users, craftspeople and fine artists, and hobbyist/DIY communities. It operates a three-channel go-to-market: direct e-commerce at polytek.com, an authorized distributor network for regional coverage, and a private label/OEM service for enterprise customers requiring custom formulations and branding. Pricing is unit-based with one-time purchases, ranging from approximately $16 for accessories to over $1,400 for specialized industrial kits. Revenue is generated almost entirely from product sales with no disclosed recurring contract or subscription component. Recent product line expansions include Bio-Based Epoxy Resin Systems, Thermoplastic Elastomers, Polyaspartic Flooring Systems, and Cured-In-Place-Pipe (CIPP) repair systems, signaling deliberate entry into sustainable chemistry, infrastructure, and flooring adjacencies beyond the legacy mold-making and theatrical base.

Products and services

• PlatSil Series - Platinum-Cured Silicone Rubber Platinum-cured (addition-cure), room-temperature curing silicones that cure to flexible, high-strength rubbers. PlatSil molds offer excellent release properties and long library life with low shrinkage. Includes standard, fast-setting, high-performance (HTS), and gel formulations. Used for mold making and casting across industrial and artistic applications.
• TinSil Series - Tin-Cured Silicone Rubber Tin-cured (condensation cure), room-temperature curing silicones for manufacturing high-performance silicone molds. Exhibits high tear strength, good release properties, and resistance to high temperatures (up to 600°F on select products). Less sensitive to cure inhibition than platinum-cured options.
• Polyurethane Materials Room-temperature curing (RTV) polyurethane rubbers, plastics, foams and adhesives. Includes polyurethane rubber for mold making, rigid and semi-rigid plastics for versatile castings, self-skinning foams (PolyFoam Series), and PolyBond adhesive for mold repair.
• EasyFlo Series - Liquid Plastics Easy-to-use, mercury-free polyurethane resins with simple 1A:1B mix ratios by volume. Super low-viscosity liquids for perfect detail penetration and bubble-free castings. Includes fire-retardant (FR) options.
• Poly-Optic Series - Clear Casting Resins Water-clear, UV-resistant polyurethane plastics for casting applications. Includes Poly-Optic 1411 and 1420 with simple 1A:1B mix ratio by volume.
• PT Flex Series - Fast-Setting Polyurethane Rubbers Rubbers specifically designed for prototyping and model making applications. Offer fast pour times (~5 minutes) and fast demold times (~2 hours). Available in Shore A20 through A85 hardness.
• Polygel Series - Brush-On/Spray Rubbers Self-thickening, brush-on polyurethane liquid mold rubber for making thin, stretchy brushed molds. Spray version available for blanket or glove molds of larger complex objects.
• PlatSil Gel Series - Silicone Gels Platinum-catalyzed silicone gels certified as skin safe. Used for theatrical prosthetic appliances, lifecasting, prop making, and medical modeling. Complies with FHSA Regulations, LHAMA, ASTM D4236, and FDA requirements.
• CPD Epoxy Resins (2110A, 107A, 2128A) Low viscosity epoxy resins for laminating, infusion, RTM (Resin Transfer Molding), casting, coating, and bonding applications. CPD brand targets industrial/composite applications such as aerospace, automotive, marine, and filament winding.
• Specialty Resin & Chemical Product Line Mold making, casting, and coating product line acquired from Specialty Resin & Chemical in September 2021. Targets hobbyists, small businesses, and DIY communities with accessible professional-grade materials.
• Private Label Services Custom formulation and branding services for customers requiring exclusive or customized specialty polymer product solutions, marketed under the customer's own brand.
