The elastomeric properties of these materials are derived from the phase separation of the hard and soft copolymer segments of the polymer, such that the urethane hard segment domains serve as cross-links between the amorphous polyether (or polyester) soft segment domains.

Choose from our selection of ultra-soft polyurethane in a wide range of styles and sizes. Same and Next Day Delivery.

The Shore A-40 and A-50 urethane systems that are described here are tough, soft, highly resilient polyurethane elastomers that have good handling characteristics and cured properties. These high physical properties make them ideally suited for applications such as bumpers, pads, flexible molds or soft parts where a high degree of flexibility ...

Thermoplastic polyurethane (TPU) is a unique category of plastic created when a polyaddition reaction occurs between a diisocyanate and one or more diols. First developed in 1937, this versatile polymer is soft and processable when heated, hard when cooled and capable of being reprocessed multiple times without losing structural integrity.

Jun 15, 2022 · Enduro SOFT is a soft polyurethane rubber casting resin with a highly flexible feel. Even with its softer feel it still has the toughness and durability of the Enduro line of Simple Resin products.

Line the walls of furnaces, freezers, ductwork, and buildings to keep heat in or out. Choose from our selection of polyurethane sheets, including metal, plastic, and more. Same and Next Day Delivery.

Super soft polyurethane foam is a type of foam material that is widely used in a variety of applications due to its softness, flexibility, and resilience. It is made by mixing polyols and diisocyanates, which react together to form a polymer that expands and solidifies into a foam.

Poron® grade 4701-40 foam is a “soft” grade material for a wide variety of applications. The unique cellular properties allow for consistent closure force and very limited stress relaxation and compression set in sealing, cushioning, and gap filling applications.

Varathane® Soft Touch Polyurethane is an acrylic polyurethane formulated to provide a soft, smooth feel to the coating surface. The matte finish protects against smudges and fingerprints. This specially designed water-based formula provides excellent scratch and stain resistance.

Jun 4, 2024 · Unlike urethane, which is soft and malleable, polyurethane is much more rigid and firm. This makes it an excellent choice for long-term use in various products. Here are some key properties: Heat Resistance: Polyurethane can withstand temperatures up to 200 degrees Fahrenheit, making it suitable for extreme heat conditions.
