This translucent silicone tubing is made of Versilic formulation SPX-50 silicone and is designed for long-term use in medical, veterinary, and pharmaceutical applications. The translucent tubing permits limited light filtration while still allowing visual flow monitoring. The Tygon Versilic formulation SPX-50 silicone construction uses a combination of silicone elastomers to provide flexibility and greater durability than typical silicone tubing. Resistant to high heats, the tubing is non-toxic and non-hemolytic to reduce the risk of inflammation in surgical applications. A smooth inner bore prevents particulate build-up and limits absorption and adsorption to help preserve fluid integrity. The tubing has a working temperature range of -75 to 350 degrees F, a durometer (hardness) of 50A, and working pressure ratings that vary by tube size. It meets U.S. Pharmacopoeia (USP) Class VI criteria for medical grade plastic materials, and U.S. Food and Drug Administration (FDA) 21 CFR 177.2600, National Sanitation Foundation (NSF) 51, and 3-A Sanitary Standards criteria for food and dairy contact for quality assurance. This silicone tubing is not designed for use as an implant material, but it is suitable for use with anesthesia and respiratory equipment, sterile filling systems, electronics equipment, appliance manufacturing, and dairy processing, among other applications. Plastic tubing is used to transfer liquids, air, or solids, and it is characterized by a round, rectangular, or square shape and a hollow center. Plastic tubing is crimp-resistant and varies in bend radius (flexibility), chemical resistance, wall thickness, durometer hardness, and temperature and pressure handling abilities. The clarity of plastic tubing may be transparent (clear), translucent (semi-clear), or opaque (solid), and the tubing's coloring may indicate suitable applications. Barbed fittings are used to connect tubing or redirect flow in a fluid handling system. Plastic tubing is used in a wide variety of industries, such as agriculture, automotive, laboratory, and medicine. Applications for plastic tubing include blood and fluid handling, peristaltic pumps, electrical and thermal insulation, analytical systems, and food and beverage handling, among others. Saint-Gobain Corporation manufactures plastic tubing for the food and beverage, chemical processing, industrial, laboratory, medical, pharmaceutical, and semiconductor processing industries under the Tygon brand in the Saint-Gobain Performance Plastics sector. Founded in 1665, the company is headquartered in Courbevoie, France, and operates 45 plastics manufacturing sites worldwide.
