- Modular Glass Fiber Reinforced Compounds Proprietary reinforced polypropylene delivering 25% increased tensile strength and up to 10% increased flexural modulus compared to traditional glass fiber reinforced polypropylene compounds.
- High Performance Fiber Reinforced Compounds High aspect ratio fiber reinforcing agents that lower compound density while substantially increasing stiffness, producing lower-density alternatives to glass-reinforced products.
- Thermoplastic Polyolefin (TPO) Compounds Custom TPO formulations engineered for toughness, durability, paintability, scratch-resistance, low-odor, and low-emissions, built and approved to customer specifications.
- Light Weight TPO Compounds Lightweight TPO compounds that reduce part weight through material density reduction and/or part thinning, supporting vehicle and packaging lightweighting needs.
- Sustainable Polyolefin Compounds (Recycled Content) One of the largest portfolios of polyolefins containing recycled content, incorporating renewable fibers and recycling technologies to meet sustainable design requirements.
- Masterbatch Compounds Polyolefin-based masterbatch solutions including custom colors, functional additives, and highly filled solutions to deliver tailored properties in customer compounds.
- Custom Color Masterbatch Polyolefin-based custom color masterbatch with expert color development services for unique colors, color effects, and colorfastness in UV and weathering environments.
- Custom Concentrates (Functional Additive Masterbatches) Polypropylene and polyethylene functional-additive masterbatches including anti-oxidants, slip agents, UV weathering additives, TiO2, and calcium carbonate.
- Flexible TPO Compounds Lightweight TPO formulations delivering toughness with flexible thermoplastic olefin for applications requiring specific touch and feel characteristics.
- Pro-Touch® Engineered Polyolefins Registered-trademark family of engineered polyolefins designed for structural applications requiring a softer look and feel, increased comfort, and design appeal, providing rigidity with soft ergonomics in a single molding process that eliminates the need for overmolding.
