Thursday February 14, 12:04 pm ET

PHILADELPHIA--(BUSINESS WIRE)--Rohm and Haas enjoys a unique reputation among specialty materials companies, being the first to commercialize many acrylic technology solutions across numerous product categories. So, it should come as no surprise that a direct result of the companys most recent work for their plastics additives customers promises cellular PVC (polyvinyl chloride) extruders and manufacturers new and greatly improved processing of cellular PVC. Rohm and Haass newest PVC processing aid, Paraloid K-445, is said to deliver remarkable processing ease as extruders adopt lines to this fast-growing innovation.

Cellular PVC is achieving wide interest across a number of industries as a lighter weight but good strength material. Said to be the fastest growing new material segment in the building products industry, cellular PVC technology is not only versatile and capable in its own right, but shines even more brightly when compared with traditional building materials. Cellular PVC is increasingly popular in such uses as exterior trim, decorative moulding, decking and millwork that embellish dwellings at every price point, from tract housing to high-end designer homes. Industry leaders like AZEK® Building Products Inc. are partnering with suppliers like Rohm and Haas to ramp up output, expand product options and advance the technology.

How this works and how well this works is said to be the key that unlocks processing ease. New Paraloid K-445s molecular architecture imparts higher melt strength, allowing for efficiency not previously seen, says Rob Martin, marketing manager, Plastics Additives, Packaging and Building Materials for Rohm and Haas.

The foam modifier improves quality and processability of cellular PVC products by improving surface quality and melt uniformity. Martin goes on to reveal that Paraloid K-445 has allowed a significant reduction in process aid loading level in laboratory, pilot, and full scale evaluations with cost efficiency delivering great benefit for users. End product advantages include surface smoothness, even gloss level and fine uniform cell structure.

As one of the major suppliers of impact modifiers, processing aids, stabilizers, lubricants, and antimicrobials for vinyl and engineering resins, the company is committed to collaborating with customers to develop innovative, high-performance materials that make theirs the preferred products for residential and commercial contractors installing deck, siding, windows, pipe, and trim products.
