C-2 Clarifying Agent

Introduction:

C-2 is the 2nd  generation sorbitol based PP clarifying agent which gives excellent clarity, gloss and surface smoothness to the PP products.  It also improves physical properties of PP products, such as heat resistance, stiffness, moisture barrier etc.
Chemical Name:  (1,3:2,4)-diparamethylbenzylidene sorbitol (MDBS) CAS No.:  54686-97-4


 Specification:

 

  White powder Appearance
  233 - 248 Melt Point (℃)
  325 min Particle size (mesh)

Application:
C-2 is a very efficient nucleation agent. It is used in homo PP or random PP for injection moulded  containers  or  thermoformed  containers  through  sheet  extrusion.    A  slight  order  may  be imparted to the product and hence it is not recommended for food packaging applications.
Recommended dosage of C-2 is 0.20-0.30 wt% in PP polymer.  Addition of  C-2 can reduce the haze of PP products from 60% to 11% for homo PP and from 50% to 9.5% for random PP.
Packaging:
20 kg net weight/Carton or as per customer request.

 

C-3 Clarifying Agent

 

Introduction:


C-3 is a new generation sorbitol based clarifying agent for PP. This product belongs to the 3rd  generation melt soluble clarifying agent type which is the most advanced clarifying agent upto date. It gives the highest clarity, gloss and surface smoothness to the PP products. It also improves physical properties of PP products, such as heat resistance, stiffness, moisture barrier etc.
C-3 in PP does not give odor problem, does not affect the taste of contained foods or liquids.
Chemical Name:  Multi-methylbenzylidene sorbitol (M-BS) CAS No.: 135861-56-2

 

  White powder Appearance
  240 - 255 Melt Point (℃)
  0.5 max Moisture content  (%)
  0.14 - 0.24 Bulk Density (g/cm3)

 

Application:


  C-3 is a very high efficient clarifying agent. It is used in homo PP or random PP for
Injection moulded containers or thermoformed containers through sheet extrustion.
Recommended dosage of    C-3 is 0.2-0.3 wt% in PP polymer. This can lead to a significant reduction in  haze from 60% to 11% for homo PP and from 50% to 7% for random PP.


Packaging:


20 kg net weight/Carton or as per customer's request.
