AbForm Ekopur-75A

Description

Polyurethane two-component system for the production of elastic rubber molded parts

AbForm Ekopur – Shore A 75A
Two-component polyurethane system for casting applications – professional resin and hardener combination

This product is a high-quality, solvent-free two-component casting system based on polyurethane resin and hardener. The material was specially developed for the production of technical castings, elastic molds, and components with high mechanical strength and dimensional stability.

Thanks to its optimal hardness (75 Shore A), low shrinkage (<0.5%), and excellent detail reproduction, it is suitable for industrial applications as well as model making and artistic work.

• Areas of Application
• Production of elastic molds for architectural concrete, plaster, wax, epoxy, and polyester resins
• Casting of technical and prototype components (bushings, dampers, vibration dampers)
• Seals, pads, and rubber-like components for varying operating conditions
• Copies of sculptures, figurines, decorative, and artistic elements with high levels of detail
• Molds for jewelry casting and small-batch production of everyday parts
• Replicas and reconstructed elements with high tensile and tear strength
• PRODUCT PROPERTIES – TEST METHODS
