EXCEEDING STANDARDS IN WATERPROOFNESS,
GIVING YOU THE ADVANTAGE


Our membranes are consistent, durable and exceed standards in waterproofness. We have set our own waterproof standard - the porelle® standard.

PORELLE® MEMBRANES PROTECTS YOU

 

Comfortable and waterproof garments, footwear and accessories are essential for you to perform at your best.

In many occupations and activities, people have to be prepared for extreme wet and cold weather conditions. However, the need for liquid protection can extend beyond normal environmental conditions. For instance, in working environments local hazards from liquid industrial chemicals to viral and blood borne pathogens must be considered.

This is why porelle® membranes are not only waterproof, but also designed to be durable - giving you the advantage.

WATERPROOF CONSISTENCY EUQALS PEROFRMANCE CONSISTENCY

We strive for high product consistency and waterproof durability in use.

 

Our membranes are designed, developed and produced in-house utilising innovative coating techniques. Their unique, uniform structure is the link to consistent waterproofness.

When laminated to a performance fabric, porelle® membranes can offer options to achieve waterproofness levels in excess of 20,000 mm in water column tests. They will retain this performance even after multiple wash cycles.

Consistency in waterproofness translates to other performance properties, such as protection against liquid chemicals, abrasion resistance, flex resistance, salt water resistance and water resistance.

We measure this consistency through the adoption and adaptation of known test standards for waterproofness.

EXCEEDING THE STANDARDS IN WATERPROOFNESS FOR TECHNICAL APPAREL

Our quality control process is built around a test regime that goes beyond the typical requirements specified in waterproof standards, such as EN 20811.

 

EN 20811 is a test method and international standard set to determine a fabric's resistance to water penetration using a Hydrostatic Head machine. The failure or end point is based on the appearance of three water droplets. So whilst a garment may be rated as having a waterproofness of 10,000 mm, the first water droplet may occur at lower values like 1,000 mm.

 

At porelle® membranes, we take a different approach to measuring waterproofness. As an example, for technical apparel we test as follows:
 

No droplets - we test to a minimum rating of 10,000 mm or high with no water droplets.

Testing after washing - all membranes are tested for waterproofness after a minimum of 10 wash cycles or higher at 60°C. Washing the membrane directly can expose potential weak spots in the membrane's structure.

Multi-point testing - for each production roll, a control sample is tested at the beginning and end with a minimum of 10 points checked for waterproofness, both before and after washing.

For a direct comparison with EN 20811 standards, please see the table below.

The porelle® membranes range has been engineered for extreme, high performance and to deliver waterproof consistency, durability and protection. All of our membranes are independently monitored by our Quality Assurance Department, which is ISO 9001 certified.
