Features and Specifications

SILASTIC RBL 2004 70 – High durometer, high transparency, fast cure liquid silicone rubber for precision molding applications with outstanding mechanical properties.

SILASTIC RBL 2004 70 Liquid Silicone Rubber is a two part, 1:1 mix ratio LSR engineered for demanding molding applications that require high mechanical strength, clarity, and short cycle times. As part of the RBL 2004 series, this material offers a higher Shore A hardness (approx. 70), making it ideal for parts requiring durability and shape retention under mechanical stress.

The A and B components are supplied strained and de aired, designed to be used as lot matched kits. For optimal processing, mixing should be done using meter mix equipment to prevent air entrapment. If air is introduced during manual mixing, vacuum de gassing is necessary. Once mixed, the material has a usable pot life of 72 hours at 25°C (77°F), allowing flexible processing windows.

The material cures rapidly at elevated temperatures, significantly reducing cycle times in high volume production environments. It is suitable for applications requiring regulatory compliance and excellent durability, including food contact, medical, and general purpose molded parts.

Key Features:
• Two part, 1:1 mix ratio
• High Shore A hardness (70) for robust performance
• High clarity and excellent surface quality
• Rapid heat cure for short cycle times
• Long pot life: 72 hours at 25°C
