PARACRIL NBR POWDER | NBR SPRAY DRIED | NBR CRUMB
Nitrile Rubber modifiers for plastics
The Paracril “P” type products are mainly used to modify PVC and ABS
and these products provide a variety of key performance and processing characteristics in a number of applications. These include, but are not limited to, flexibility, permanent plasticization, and soft-touch (in PVC), modulus, and impact strength. These modifiers also provide resistance to oil, chemicals, and resilience in changing temperatures. They are produced by chemical crosslinking or conversion branched. The crosslinked grades have varying degrees of reduced mill shrink to as low as 5% versus linear grades of over 35% mill shrink. These grades offer benefits in thermoplastic modification for lower compression set and green strength improvement. Dynasol produces a range of Paracril Nitrile “P” powder rubber products with a particle size of 0.5 -1.0 mm depending on the product.
Paracril Spray Dried Powder
Paracril NBR “SD” Powder, typically <0.10 mm in size, is used in friction products.
The NBR for these applications is typically a higher acrylonitrile content, high viscosity
modifier primarily used to modify phenolic resins in brake pads, linings, or clutch facings. They provide excellent heat resistance and serve to reduce noise and vibration during the service life of friction materials The Paracril SD acts as a secondary binder that provides a higher coefficient of friction, antifading performance, plus fuel and oil resistance.
Nitrile Rubber for Adhesives Applications
Paracril Nitrile Rubber crumb and bale products
Paracril is an ideal polymer for solvent-based cement for use where oil resistance and good adhesion characteristics are needed. By compounding with other polymers, resins, softeners, and curatives, the properties of the dried adhesive film can be adapted for a wide range of applications. The correct grades of Paracril can be easily solvated and have excellent stability, depending on the polymer breakdown, concentration, and solvent type. Paracril for adhesive applications is available in “crumb” form (6-12 mm size) for ease of dissolving, or in traditional “bale” form.
