WEB EXCLUSIVE: A new rigid PVC compound with a specially developed UV-blocking formulation from Teknor Apex Co., Pawtucket, R.I., reportedly provides good clarity (less than 15% haze), as well as high gloss and toughness, for photobioreactor and other outdoor tubing applications.

 

The UV blocking formulation in Apex RE 9118A compound is said to substantially reduce the harmful effects of UV radiation on the PVC while permitting passage of wavelengths that are essential in processes like algae farming for biofuels. The compound’s tensile, flexural, and impact properties are reportedly comparable to those of standard general-purpose rigid PVC.
