Membrane Filters: Selection, Production, and Use

by ISP | February 23, 2018

Membrane filters allow the flow of fluids or gases while preventing the passage of particles and microorganisms. They are made of porous plastic films that retain particulates larger than a defined pore size. In other words, substances that are too large to fit through the filter’s pores are retained on the membrane’s surface and excluded from the purified stream.

Membrane filters are fabricated with precision die cutting, a manufacturing method that uses metal tools called dies to cut microporous plastics into precise shapes with specific geometries. Die cutting supports low-to-high volume quantities and is fast, accurate, and efficient. Engineers and designers can choose from various membrane materials that are strong, thermostable, and chemically and biologically clean.

Porex Wicking Material: Die Cut Components for Wicking Fluids

by ISP | December 11, 2017

Die cut components for wicking fluids are used in medical, bioscience, and filtration applications. They are made of porous plastic materials with open-celled structures and omni-directional pores. Depending on your application, a specific POREX wicking material may be required. POREX, a trademark of POREX Corporation, is a family of porous thermoplastics that support precision die cutting.

Advantages of Porex Wicking Material

POREX wicking material is designed to optimize fluid transfer (wicking) for a specific end-use requirement. The wick’s open-celled structure supports the control of liquid volume capacity and fluid transfer rates. The wick’s surface energy can enhance media capillarity, the rise or depression of a liquid in a small passage such as open-celled, omni-directional pores.

ISP Completes Transition to ISO 9001:2015 & ISO 13485:2016

by ISP Marketing | September 25, 2017

 What is an ISO Certified Die Cutter?

ISO certifications for die cutters demonstrate a commitment to quality. Any manufacturer can claim to provide quality die cut products, but ISO certification proves that the company uses an approved quality management system (QMS), a set of policies, processes, and procedures for planning and execution in the organization’s core business area. ISO certified companies follow the plan-check-do-act (PCDA) model and are effective, efficient, responsive, and well-managed.

Shelf Life of Rubber Products

by ISP | March 29, 2016

Rubber products can remain in inventory for long periods of time. Shelf life, the storage period prior to part installation, varies by elastomer type. Storage conditions such as temperature, humidity, ozone, and exposure to light also affect the shelf life of rubber products. By understanding these factors and best practices, buyers can make informed decisions about sourcing elastomers and storing die-cut seals, gaskets, and O-rings.
