Water Treatment Membranes 

Udel® polysulfone has long been the industry standard for making the support layers used in the production of RO and NF thin-film composite membranes. Udel P-3500 LCD MB is used around the world for making high-pressure water filtration membranes.

Key Features

• Cost-effective processing by solution casting
• Excellent mechanical properties
• Stable at pH levels from 2-13
• Outstanding hydrolytic stability
• Excellent caustic resistance
• Good resistance to moderate concentrations of chlorine
• Low levels of extractible and insoluble materials
• Global agency approvals

Solef® PVDF has become an industry standard for submerged UF and MF hollow fiber membrane systems, especially in the rapidly growing membrane bioreactor (MBR) segment.

Key Features

• Outstanding processability with a large number of grades
• Available in narrow molecular weight ranges
• Excellent impact strength and mechanical properties
• Good resistance to organic fouling
• Stable at pH levels from 1 to 11
• Excellent chlorine resistance
• Low level of insolubles
• Excellent UV resistance
• Very high purity and low level of extractibles
• Global agency approvals

Udel® PSU and Veradel® PESU are Sulfone Polymers for Membranes used specifically to make encased UF and MF membranes.

Algoflon® DF powders are easily expanded after the extrusion of the polymeric matrix without the use of soluble fillers, foaming agents or chemical additives. This process generates the physical creation of a huge number of small pores in the structure of an object made of PTFE resulting in new outstanding properties.

In particular uniaxially stretched tubes are used for the manufacture of hollow fiber membranes for liquid filtration(such as water treatment),while multiaxially stretched membranes have several applications which include gaskets, filters for filtration of gases and liquids and membranes for fuel cells.
