Description
[Saint-Gobain] A registered trademark for a series of flexible tubings. The original Tygon® tubing, now called Tygon® Laboratory tubing, is made from polyvinyl chloride plasticized with di-2-ethylhexylphthalate (DEHP). Tygon® laboratory tubing is not recommended for use in conservation (Williams 1987). The various kinds of PVC tubings contain from 22-52% of the oily plasticizer. As the tubing ages, the plasticizer will migrate to the surface producing visible oily deposits that can easily transfer to any contacting material. Additionally, polyvinyl chloride will degrade with time slowly releasing hydrogen chloride gas. Other types of Tygon® tubing include:
- Tygon® Inert tubing: PVC with FEP inner liner
- Tygon® Silicone tubing
- Tygon® High purity tubing: plasticizer free
- Tygon® MPF series: PVC free flexible tubing
