Teknor Apex Sarlink® 3440 Thermoplastic Elastomer
Categories: Polymer; Thermoplastic; Elastomer, TPE; Thermoplastic Olefinic Elastomer (TPO)

Material Notes: A NSF certified, low hardness and multi-purpose thermoplastic elastomer (black and natural color) featuring excellent fluid resistance and high temperature performance. It can be processed by injection molding, blow molding or extrusion for applications in contact with potable water, such as pipes, fittings and appurtenances.

Processing and Handling (See more in property table)
Sarlink® 3440 is a polypropylene based elastomer, which can be processed on conventional thermoplastic equipment for injection molding and extrusion. This product has a wide processing window in most applications. Melt temperatures from 360°F to 430°F can be used. Do not exceed 450°F. Drying is recommended for extrusion and blow molding and any time the material is used from an unsealed package.

Extrusion screen pack is 20 to 60 mesh.

PURGING
This product has excellent melt stability. Empty the barrel for idle periods of thirty (30) minutes or longer. Purge thoroughly before and after use of this product with polyethylene or polypropylene.

RECYCLING/REGRIND
This product can be reprocessed. Physical properties are generally not degraded. Dry regrind prior to reprocessing.

COLORING
The use of polyolefin based color concentrates is recommended. Apply back pressure in injection molding to disperse color.

BONDING/ASSEMBLY

STORAGE and HANDLING
This product is available in 55 lb. foil lined bags (up to 2,200 lbs. per pallet) or 1,100 lb. polyethylene lined gaylords. It has a storage life at normal temperatures of several years.

Sarlink® was sold from DSM to Teknor Apex
