PNBR GM50 USES is very wide, is the brake pads. Footwear, tube sheet, film, profile pipe fitting
Fine raw material of wood plastic and mold products.PVC powder NBR elastomer modified agent GM50 is introduced
PNBR GM50 modified polyvinyl chloride (PVC) product quality improve the economic benefit, the varieties of upgrading
Improvement of polyvinyl chloride (PVC) product quality. Improve the economic benefit, the varieties of upgrading
Products use sample
Sports shoe work boots, safety boots car window seal products and seal
The special performance of PNBR PGM50 / PVC mixture:
Heat resistant, cold resistant, skid resistance to oil, soluble and deflection
Plasticizer migration compression permanent deformation dimension stability
The characteristics of the PNBRGM50 elastic modifier
- liquid powder particle size, less than 1 mm. With the PVC intermiscibility is wonderful - the use of general PVC processing technology
- the main features are:
For a long time to keep the original performance of the PVC clear rubber performance. Improve physical performance. Improve chemical resistance. Improve the processing performance
PNBR GM50 modifier
PNBRGM50 liquidity is a high-quality powdered butadiene acrylonitrile polymer, is to improve plastic especially half hard and soft PVC plastic performance specially developed for processing raw materials.
PNBR GM50 and blending of PVC material, in extrusion and injection molding can be directly used as feed, in addition, this kind of mixing material used for rolling processing is also very ideal.PNBR GM50 added into PVC mixture can enlarge machining range and increase productivity.
PNBR GM50 and soft PVC mixture can improve the physical properties of plastics, especially kneading deflection, abrasion resistance, compression permanent deformation performance and recycling, at the same time also can strengthen the resistance to solvent, grease and the performance of the plasticizer leaching.This kind of mixing material can meet the requirements of higher, can be used to replace other thermoplastic materials.
Method of use:
A) high speed mixing method
(1) in high speed mixer will be PVC and other dry components (PNBR GM50 except), mixed in advance, until the temperature of 70 ~ 70 ℃.
(2) under the same high speed add liquid plasticizer.
(3) under 120 ℃ unloaded into the mixture cooling segment.
(4) cool to 40 ℃ / PNBR GM50.
(5) the discharging.
B) low speed mixing method
(1) in low speed mixer mixing, made of PVC and other dry components (PNBR GM50 except) heating to 70 ~ 80 ℃.
(2) to add liquid plasticizer, make temperature rise to 100 ℃.
(3) the unloaded into the mixture cooling segment.
The temperature dropped to 40 ℃ (4) adding PNBR GM50.
(5) the discharging.
