What is REACH? The European Union has lead the way in “phasing out” many hazardous chemicals from consumer products. The vehicle for this legislation is known as REACH. Most PVC Tubing is NOT REACH Compliant Flexible PVC tubing, also commonly known as flexible vinyl tubing is used widely in everything from medical devices to soda and beer tubing in restaurants. What is DEHP? PVC tubing is made flexible by adding chemicals known as plasticizers. A phthalate compound known as… Read More »
Silicone is used in a variety of medical instruments and equipment which must be sterilized before use. Three main methods of sterilization can be considered: steam sterilization (autoclave), irradiation and ethylene oxide. Steam Sterilization by Autoclave Steam sterilization is typically carried out in an autoclave at 121°c (250°F) for 15 minutes, although other conditions are often used (Rogers, W., 2005). Silicone tubing may start to become gummy after having being steam sterilized several times and should then be replaced. Irradiation:… Read More »
What is the Difference Between LDPE and LLDPE? Low Density Polyethylene (LDPE) and Linear Low Density Polyethylene (LLDPE) are both inexpensive polymers with widely favorable mechanical and chemical resistance properties. Tubing made from both polymers is broadly used, particularly for water, chemicals and gases. Unlike with many other plastics, plasticizers are seldom necessary to obtain flexible products, such as tubing. Both plastics are highly stable with low toxicity. In fact, many grades can even be used for food-contact and medical… Read More »
