N Resin Flexibility Tenacity Reinforcement Agent
Carboxyl Nitrile Rubber Powder
(A Brief Introducetion)
Carboxyl
nitrile rubber power is produced by grafting the carboxyl-bon on the
outer edge of nitrile to form a nuclear shell structure.After grafting, the
micelle becomes a honeycomb type and the light wave can pass through
the micelle, so it can be used to make fransparent prouduce.Being white
in colour and fine in grain, this product is quite compatible with
polyvinyl chloride(PVC), phenolic resin(PE) ABS resin, nylon(PA) and
ethylene-vinyl acetate copolyme(EVA).It can be pelletized by feeding
it into the single-screw extruder, thus saving labour, time and energy
with fangiblr result.if can be substituted for p83, Du Pont 741, chlorinated
polyethylene(CPE) and also for MBS as PVC fransparent products.This
product has passed the qualification test jointly conducted by Nanjing
Science and Technology Commission and Economic Commussion and has
been reported to the higher authorities for a major item of new product
at national level.
This
product can improve the elasticity, oil resistance, low-tem-perature
flexture resistance, antiskid, abrasion resistance, compression and permanent
deformation resistance and aging resistance of the PVC products.If
can prevent the low-molecular plasticizer from moving to the surface
and homogenize the millipores of the foaming products by increasing
the melt strength.By mixing with phonolic resin, its impact resistance
and clongation can be improved, thus obtaining an impact and vibration
resisting product which is particularly suitable for making brake-shoes
of high-speed train and limousine.Such product is not only in abrasion
and great in friction coefficient, but also vinrationless. By mixing
with PE or PP, its elasticity and impact strength can be distinctively
improued.
1.
Carboxyl nitrile rubber power has a song absorbing action orlow-molecular.For
the production of PVC soft products.It is imperative to mix first
with dry-powered assistant and then add low-molecular plasticizer
(such as DOP), After PVC has completely absorbed the low-molecular
plasticizer, then add this product.If is preferable to add this product
at below 80℃ in order to avoid agglomeration.For the production
of PVC hard products, the mixing can be carried out simultaneously.
2.
This product is contained in a PE filmy each of 5kg.And two bags
are contained in a net weight of 10kg.Take care not to stack too
high during storage or fransportation, in order to avoid agglomeration
of the power.
