Features and Specifications

SILASTIC RBL 2004 30 – High transparency, medical grade, fast cure liquid silicone rubber (LSR) for molding and injection molding applications with superior mechanical and regulatory performance.

SILASTIC RBL 2004 30 Liquid Silicone Rubber is a two part, 1:1 mix ratio LSR developed for applications that demand high clarity, excellent mechanical strength, and fast cycle times. This product supports a wide range of molding processes, including injection molding, and offers a balanced pot life with rapid heat cure, making it suitable for both general and high performance uses. With a durometer of 30 Shore A, this soft but strong LSR provides excellent flexibility in part design and meets stringent regulatory requirements.

Parts A and B must be thoroughly mixed in equal proportions. For best results, use meter mix equipment to avoid air entrapment; if air bubbles are introduced, vacuum de gassing is necessary. This material cures rapidly under heat—e.g., a 2 mm cross section cures in 6–10 seconds at 200°C (392°F). Cure time will vary based on part geometry and process temperature.

Key Features:
• Two part, 1:1 mix ratio LSR
• High transparency and superior surface quality
• Low compression set
• Rapid heat cure (6–10 sec at 200°C for 2 mm thickness)
• Durometer: 30.0 Shore A
• Specific gravity: 1.119
• Tensile strength: 8.2 MPa (1185 psi)
• Elongation at break: 986.8%
• Excellent part design flexibility
• Supports injection and compression molding
