What SEKISUI KYDEX, LLC does

SEKISUI KYDEX, LLC is a US-based specialty thermoplastics manufacturer and wholly-owned subsidiary of Japanese conglomerate SEKISUI Chemical, headquartered in Bloomsburg, Pennsylvania. Founded in 1965, the company designs and produces proprietary fire-rated thermoplastic sheet products (KYDEX and ALLEN brands) used in highly regulated industries including commercial aviation interiors, mass transit (rail and electric buses), medical devices, building interiors, and agricultural/heavy equipment. Its core technology involves thermoplastic sheet extrusion and thermoforming of plasticizer-free polymers with fire, smoke, and toxicity (FST) compliance, supported by an in-house FSTLab testing infrastructure, an appLab rapid prototyping center, and a designLab color and visualization center utilizing X-Rite TAC technology.

The company operates a B2B go-to-market model combining direct enterprise sales to manufacturers, OEMs, and airlines with a global authorized distributor network and dedicated customer portals for KYDEX and ALLEN brands. Revenue is generated primarily through thermoplastic sheet sales and injection molding resin sales (e.g., KYDEX T-IM), with an emerging revenue stream from fabricated finished parts produced under the Quick Response Manufacturing (QRM) model, which reduces standard four-week lead times to one week. Proprietary technologies such as Infused Imaging (Crystal Cabin Award-winning image embedding), KYDEX ION Technology (antimicrobial formulation), and KYDEX surfaceGrip (anti-slip) provide product differentiation. Notable customer engagements include Ford/GE Healthcare (50,000 ventilators), CAE Air1 (10,000 ventilators), Proterra (electric bus interiors), Alaska Airlines, and Canfield Scientific, demonstrating the company's positioning as an integrated materials-and-prototyping partner rather than a pure extruder.

Revenue model

1. Thermoplastic Sheet Sales: Sale of proprietary KYDEX® and ALLEN® branded thermoplastic sheet materials to manufacturers, fabricators, and distributors. Products include KYDEX® T, KYDEX® 6200, KYDEX® 6503, KYDEX® Lumina, ALLEN® ABS, and specialty formulations including antimicrobial (ION Technology™) and anti-slip (surfaceGrip™) variants. Materials sold in sheets of various gauges and colors, with custom color matching available.
2. Fabricated/Finished Parts: Step beyond traditional sheet sales — SEKISUI KYDEX also produces fully finished, ready-to-assemble fabricated parts for customers through its appLab innovation center, serving as a strategic integrator. This is a shift from the traditional extruder model enabled by the QRM manufacturing approach.
3. Injection Molding Resin Sales: Sale of injection molding resin materials (e.g., KYDEX® T-IM) alongside sheet products, harmonizing multiple material types in single applications for customers.

Core offering

SEKISUI KYDEX manufactures and sells proprietary KYDEX® and ALLEN® branded thermoplastic sheet materials, formulated without plasticizers and engineered for fire, smoke, and toxicity (FST) compliance in highly regulated industries. The company serves aviation, mass transit, medical, building interiors, agricultural/heavy equipment, and emerging technology markets through direct sales and an authorized distributor network, supported by in-house innovation centers (appLab™, designLab®, FSTLab™) that provide rapid prototyping, color/design development, and FST testing. Beyond raw sheet extrusion, SEKISUI KYDEX also produces fabricated finished parts and injection molding resin, operating a Quick Response Manufacturing (QRM) model that compresses standard 4-week lead times to 1 week.

Product overview

SEKISUI KYDEX is a global thermoplastics leader that innovates and creates sustainable thermoplastic material solutions. The company operates two core product brands—KYDEX® Thermoplastics and ALLEN®—alongside proprietary technologies including Infused Imaging™ (award-winning imagery embedding process), KYDEX® Injection Molding services, and specialty formulations like KYDEX ION Technology™ (antimicrobial) and KYDEX® surfaceGrip™ (anti-slip). These materials serve demanding markets including Aviation, Mass Transit, Medical, Building Interiors, Ag & Heavy Equipment, and Emerging Technology. The company supports its materials through three Innovation Centers (appLab™ for rapid prototyping, designLab® for color and design development, and FSTLab™ for fire, smoke, and toxicity testing) that enable customers to move from concept to production-ready parts using Quick Response Manufacturing (QRM) methodology.
