In semiconductor cooling, precision chemical dosing, and pharmaceutical processing, tubing is the critical link ensuring zero contamination and high-pressure safety. Industrial-Grade Platinum-Cured Silicone Tubes are engineered for extreme environments through advanced cross-linking and mechanical design.
Material Science: Addition Curing and Thin-Walled Cylinder Stress Model
Platinum Curing & Purity Advantage: Unlike peroxide curing, platinum curing is an addition-cured reaction yielding zero low-molecular-weight by-products. This results in an ultra-smooth, inert inner wall, essential for Ultra-Pure Water (UPW) and sensitive chemical transport.
Hoop Stress in High-Pressure Systems: To prevent tube failure under pressure P, hoop stress (σ) is a vital engineering metric: σ = (P * d) / (2 * t) (Pure text: σ = (P * d) / (2 * t), where σ is Hoop Stress, P is internal pressure, d is inner diameter, and t is wall thickness) Lixing’s tubing leverages high cross-link density to absorb dynamic pressure spikes without bursting.
Thermodynamic Stability: The Si-O-Si bond’s high energy (444 kJ/mol) allows the tube to remain flexible at -60°C and stable at +200°C, offering superior aging resistance against ozone and UV.
Industrial Applications
Semiconductor Chillers: Routes coolants reliably during extreme thermal cycling with zero particulate shedding.
Peristaltic Pumps: Provides long flex-life and chemical inertness for accurate fluid dispensing.
