Polyline Industries have developed and manufactured an advanced range of moulded polyethylene products manufactured from linear Medium-Density Polyethylene (MDPE), a lighter material with better impact resistance than High-Density Polyethylene (HDPE).
Standard features of HDPE
- Inert - Will Not Corrode
- Flexible
- Inbuilt noise absorption
- Durable & impact resistant
- Lightweight
- Low maintenance
- Low friction coefficient (0.02)
Advanced features of the moulded MDPE products
A more robust moulded cylinder which is:
- Seamless – products therefore have less welds
- Inherently round – Rather than fabricated & inherently flat
- Double Rings – Ensures vent bags will not blow off that even under the highest pressure
- UV Stable for outdoor storage
- Fire Retardants & Anti-Static additives available
- Compatible Joining System
