DEMAND:

• Improving the resilience and durability of the product.
• Better outdoor performance
• Cost reduction

Problems:

• Insufficient toughness
• White ring appears at socket
• After outdoor exposure, the pipe becomes brittle
• High production costs, need to add more CaCO3 to win competitor

Root Cause Analysis:

The original formula： made the production batches unstable, resulting in low efficiency and increased costs.

Low toughness agent efficiency： resulting in insufficient toughness

Key Benefits of RALLYCHEM’s Formulation

1、Continuous Lubrication Protection

Provides consistent lubrication during the entire processing cycle (beginning, middle, and end).

2、Superior Anti-Precipitation Performance

Better resistance to precipitation compared to traditional formulations.

3、Reduce the cost

Polyester Homopolymer enable the manufacturer to add in more CaCO3 without losing the property.

4、Wider Processing Range

Reduces the frequency of degradation and provides more stable processing conditions.

5、Superior Shear Resistance

Better shear resistance compared to traditional formulations, allowing for the addition of more calcium carbonate.

6、Suitable for Large Diameters

Can be effectively used for large diameter pipes(Dn200/315/630).

Key Improvement: Enhanced Toughening, Reduce cost

RALLYCHEM’s formulation increases the toughening efficiency, resulting in significantly improved product durability, and reduce the cost via adding more CaCO3.
