- PSU caps and PTFE pouring rings offer greater thermal and chemical resistance than the equivalent polypropylene components
- Screw cap seal with PTFE faced cap liner for efficient sealing
- The matching PTFE pouring ring permits drip-free pouring and clean, safe working
The material used for this GLS 80 closure is a special compound based on polyarylsulphone. As a result, the chemical, thermal and mechanical properties of the material are improved compared to polypropylene. Thanks to the shortened triple thread, the DURAN® GLS 80® bottle can be opened or closed with only a three-quarter turn. The seal, which is coated on both sides with PTFE, ensures the bottle can be tightly sealed (cap liner: Platinum-cured silicone). A matching PTFE pouring ring is also available, permitting clean, drip-free use. White PSU GLS 80® wide-mouth screw cap (cap liner seal) and drip free, PTFE pouring ring for GLS 80® bottles.
