Clarifying Agent 3940 CAS NO 54686-97-4 CAS NO 81541-12-0

Clarifying Agent 3940 CAS NO 54686-97-4 CAS NO 81541-12-0

Applications:
1.It is MDBS,Sorbitol based clarifying agent and nucleating agent for polyolefins,particularly for polypropylene(PP),linear low density polyethylene(LLDPE),some high density polyethylene(HDPE);
2.It provides polyolefins very fine and uniform size crystallites which is smaller than the wavelength of visible light,so it can increase clarity,lower haze & improve gloss and surface smoothness of them.

Product Details

Clarifying agent 3940 CAS NO 54686-97-4 or 81541-12-0 or 87826-41-3

Improve clarity, surface smoothness and crystallization rate for polyolefins, gelling agent,fluidity control agent.


It is a MDBS, Sorbitol based & second generation clarifying agent for polyolefins, particularly for PP, LLDPE, some HDPE. It is highly effective in improving transparency to homo or random PP. besides, it also can enhance mechanical characteristics of PP such as crystallization rate and flexural modulus too. it can be used as a monomer-type gelling agent, fluidity control agent. commercial production. sample is available. welcome to try our products.

Applications:

1.It is MDBS,Sorbitol based clarifying agent and nucleating agent for polyolefins,particularly for polypropylene(PP),linear low density polyethylene(LLDPE),some high density polyethylene(HDPE);

2.It provides polyolefins very fine and uniform size crystallites which is smaller than the wavelength of visible light,so it can increase clarity,lower haze & improve gloss and surface smoothness of them.

3.It also can increase crystallization rate of polyolefins which result in shorter cycle times,lower fabrication costs and increased production capacity.flexural modulus of polyolefins can be improved by clarifying agent 3940 too.

4.It is a clear nucleating agent suitable for medical PP like injector.it is also suitable for wide ranging thin injection molded products (such as storage containers,CD/DVD cases,jewel boxes and food containers etc),blow molding,film or sheet extrusion process;

5.It can act as monomer-type gelling agent,fluidity control agent or the like

6.It can be added directly to polyolefins powder also can be produced as 2.5~5% masterbatch.Dosage for reference: 0.2%~0.4%


Features:

1.Increase clarity and lower haze in polyolefins

2.Improve gloos and surface smoothness

3.Faster molding cycles

4.Increase flexural modlus and tensile strength

5.Increase heat distortion temperature

6.Non-toxic,FDA approved for use in food contact applications as its regulation

7.Less dimensional variances in molded parts.

8.Disperse completely and evenly in plastics as it is organic in nature and melt well during normal process
