APSOseal® Elastomer Profiles

ELASTOMER PROFILES Elastomer profiles – everything you need from a single supplier Elastomer profiles are employed as sealing, covering and protective elements. Compression of a cross-section, a hollow space or a lip initiates a sealing sequence. This shape change and the elastic behavior of the profile material create a seal. The natural resilience of elastomeric materials provides a virtually constant sealing force. Consulting and engineering The specialists at Angst + Pfister have extensive experience in the area of elastomer profiles. Take advantage of our expertise by turning to us for...

ELASTOMER PROFILES Materials and compliance certifications Requirements placed on elastomers Each elastomer material has deployment constraints with regard to its behavior during exposure to hot and cold temperatures, its resistance to substances with which it comes in contact and its resistance to weathering. Depending on the deployment, our elastomer profile seals feature approval and compliance certifications for use in areas such as the food and medical industry (FDA, etc.) and the drinking-water sector (KTW, etc.), or meet fire protection regulations for the rail vehicle construction...

Profile shapes and tolerances Profile shapes During the manufacturing of extruded elastomer profiles, significant dimensional deviations arise caused by swelling of the profile cross-section as it exits the extrusion die and by shrinkage and deformation during subsequent vulcanization. Hence, the design of the seal geometry is the absolutely crucial determinant of seal functionality. Selecting the ideal profile shape takes a lot of experience, and the development work is very time-consuming. Shorten the development phase by taking advantage of our longstanding experience and comprehensive...

Fabrication Joining possibilities Angst + Pfister offers a variety of fabrication processes that enable extruded profiles to be bonded to frames or rings. The processes depend on the material employed. For rubber types such as NR, EPDM, CR, NBR, FKM, VMQ, etc.: • injection; • autoclave vulcanization; • hot-air vulcanization (adhesive mixture/foil); • bonding (FKM and EPDM with limitations). For thermoplastics such as TPU, PVC, etc.: • hot plate welding; • bonding. Self-adhesive backing Profiles can be equipped with a self-adhesive backing, whether as an assembly aid or as a functional...

ELASTOMER PROFILES Profile labeling and surface treatments Profile labeling Logos, item numbers, manufacture dates, batch numbers, etc., can be printed on profiles either directly during extrusion or afterward by hand using a pad printing process. Surface treatments Surface treatments are applied to profiles for purposes such as to prevent them from sticking together, to facilitate installation, to reduce coefficients of friction or to enhance resistance to destructive influences. Talcum powdering Powdered talcum is applied to the profile surface. This prevents profiles from sticking...
