1. Resistance to Caustic and Acidic Cleaning Agents
Most CIP cycles involve 2% to 5% Sodium Hydroxide (Caustic Soda) or Nitric Acid at elevated temperatures. Standard rubber or low-grade PVC will swell, lose tensile strength, and eventually "gum up" or crack.

• The SOSHH Advantage: Our specialized Polyurethane (TPU) formula is chemically stable against a wide range of common industrial detergents.
• No Material Degradation: SOSHH connectors maintain their 45.0 MPa tensile strength even after repeated exposure to cleaning chemicals, preventing "thinning" of the connector walls.

2. Thermal Resilience During SIP (Steam-In-Place)
Steam sterilization typically reaches temperatures of 121C to 135C. This thermal shock causes many elastomers to lose their "memory" and become permanently deformed.

• PUHT Series: For lines requiring steam sterilization, our PUHT (High-Temp) connectors are the ideal choice, maintaining their shape and sealing integrity up to 150C.
• Mirror-Smooth Surface: Because the material does not degrade, the internal surface remains smooth, ensuring that no "micro-pockets" are created where bacteria could hide.

3. Hydrolysis Resistance: Preventing "Water Damage"
Low-quality TPU often suffers from hydrolysis—a chemical breakdown caused by long-term exposure to hot water and moisture. This results in the material becoming brittle and snapping like a cracker.

• Ether-Based TPU: SOSHH utilizes high-grade ether-based TPU, which offers superior hydrolysis resistance compared to cheaper ester-based alternatives.
• Longevity: This ensures that your connectors remain flexible and transparent, even in the humid, high-moisture environments common in food processing.

4. Visual Inspection: The "Transparency" Factor
One of the best indicators of a connector's health is its clarity. When a connector turns yellow or milky, it is a sign of chemical degradation.

• UV and Chemical Stability: SOSHH connectors are designed to remain clear longer. This allows your maintenance team to perform visual inspections of the internal flow and the seal's condition without having to dismantle the entire joint.
