Sales Spike for Schreiner ProTech Pressure Compensation Seals

Printable, steam jet-resistant PCS for automotive applications

Published: Tuesday, January 31, 2023 - 12:00

(Schreiner Pro Tech: Blauvelt, NY) – Schreiner ProTech, a Germany-based global leader in developing and manufacturing innovative functional labels with value-added benefits for the automotive and engineering-based industries, has seen significant growth for a special series of pressure compensation seal (PCS) solutions. Thanks partly to the rapidly expanding electric vehicles sector, the company has seen a 32-percent year-over-year sales uptick for its PCS HighProtect range: the world’s first line of printable, steam jet-resistant pressure compensation seals.

A pressure compensation seal is a watertight, breathable membrane used to vent electronic housings, similar to a valve. The membrane ensures effective pressure compensation while preventing the intrusion of water, dust, or dirt into the housing. Despite their minimal height, the robust PCS HighProtect products can withstand even industrial-strength steam-jet cleaners.

Notably, e-vehicles need robust, durable pressure compensation solutions in several areas—including the battery and driving column—resistant to steam-jet cleaning. Here, it’s increasingly important for such solutions to be lightweight and small to simplify production processes and save on warehousing space and shipping costs. In various shapes and sizes, PCS High Protect provides solutions spanning several functions, including charging protection, battery and motor production and lifespan management, and components marking and sealing.

Electric or otherwise, PCS HighProtect offers automotive OEMs and suppliers a venting solution suitable for customized in-line printing, allowing them to eliminate a process step and save associated material and maintenance costs. In this fashion, the PCS serves dual roles of identification and protection while streamlining production.

Due to its customized design, PCS HighProtect visually functions as a marking label. And though the pressure compensation membrane’s small ventilation hole—necessary for emitting heat produced during electronics operation—doesn’t show through the wear-resistant top film, the PCS still effectively serves its original protective purposes.

PCS HighProtect is offered via a modular concept that makes multiple combinations possible for specific customer needs. Among other options, the seals can be round or angular, long or short, and incorporate multicolor logos and QR codes.
