Thermoplastic Olefinic Elastomer (TPO)
Teknor Apex Company
产品说明：
A high hardness, multi-purpose thermoplastic elastomer featuring excellent compression set and high temperature performance. Sarlink® 3145D can be processed by injection blow molding, molding or extrusion for applications such as grips, seals, gaskets, profiles and other articles.
Processing and Handling (See more in property table)
Sarlink® 3145D is a polypropylene based elastomer, which can be processed on conventional thermoplastic equipment for injection molding, extrusion and blow molding. 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
Thermal bonding techniques can be used to form high strength bonds. Adhesive bonding can be achieved with specialized adhesives. Bond strength is limited due to the polypropylene base of this material.
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. Please refer to the Material Safety Data Sheet for this grade prior to first time handling.
