Homopolymer PP Clarifying Agent

A0003 is a Clarifying Agent that used in Homopolymer Polypropylene(PP), which can greatly improve the crystallization speed and structure of Homopolymer Polypropylene(PP).

Characteristics of A0003

- Improve Heat Deflection Temperature of Homopolymer
- Polypropylene (PP) to replace the High Heat polymer;
- Improve Transmittance;
- Improve Gloss and Product Appearance;
- Improve Impact Strength and Flexibility etc.

A0003 enhanced the properties of Homopolymer Polypropylene (PP) as follows: (with 2% of A0003 added)
Properties Testing Method Improved Ratio
Light Transmittance ASTM D1003 +60%
Gloss ASTM D523 +8%
Heat Deflection Temperature ASTM 638 +30%
Tensile Strength ASTM 638 +16%
Flexural Strength ASTM D790 +25%
Izod Impact Strength (notched) ASTM D252 +20%

Homopolymer Polypropylene (PP)has a low price, high gloss, high flexibility but its low transmittance and low heat deflection temperature restrict its applications when using on the transparent and high heat products. In order to solve this problem, we decide to supply Homopolymer PP Clarifying Agent A0003. Clarifying Agent is in compliance with the regulations of FDA which is ideal for food contact applications.

3. Purging Agent (C1668 file)

C1668 Purging Agent

C1668 is a high molecular weight polymer based plasticised mineral purging agent that combines the benefits of the best three cleaning processes. Firstly, its expansible and foaming effects during melting state, allows all parts of screw and barrel being thoroughly cleaned. Its plasticised mineral brush up function can effectively clean up the screw and barrel without causing any harm. Thirdly, its extremely dissolving ingredients, can eliminate the attached plastic material, pigment and waste, thus minimizing the chance of erosion.

As C1668 can bring out the combined functions of the three cleaning processes, higher performance and better cost-effectiveness are therefore expected.

Special Characteristics:
- Increased Productivity - Since the dirt could be removed completely by using C1668, the number of times that the screw need to be clean is largely reduced, thus increasing the productivity.
- Reduced clearing cost - With its superior cleaning power, a few drops would be enough to get the screw fresh and clean, thus 60%-80% time can be saved comparing with those traditional methods.
- Reducing the occurrence of defects - Periodic use will prevent black spots occur, therefore less defects could be expected.
- Powerful performance - Its special ingredients will make the screw looks ever polished and new.
- Wide range of Applications - Well suit to use with numerous plastic resins, ABS, PS, PE, PP, TPE, PVC, PA, PBT, PC etc…
- Reliable and Secure - With its moderate hardness, the screw and the melting tub will be less likely damaged.
- User-friendly - Easy to control by following a step-by-step instruction.

Attention: When heated, the foaming properties of C1668 may force the plastics materials flow out from the injection gap, please be careful.
