Macrotone Silicone Masterbatch

TDS Ref ID: 1532

Description:

Macrotone Silicone Masterbatch is a high-concentration silicone additive acting as an internal lubricant and processing aid in polymers.
This additive reduces friction, improves melt flow, and enhances the surface properties of the final product.
It helps in overcoming processing challenges and achieving superior product aesthetics and performance.
Ideal for applications requiring improved slip, anti-scratch, and easy mold release properties.

Key Advantages:

Reduces friction and wear of plastic parts.
Improves processability (reduces extruder torque and pressure).
Increases surface lubricity and anti-stick properties.
Enhances surface quality (reduces flow lines and increases gloss).
Reduces production cycle time and energy consumption.

Recommended Processing Considerations

Addition: Macrotone Silicone Masterbatch can be directly added to the polymer blend during compounding or at the main extruder feeder. Ensure thorough mixing for optimal dispersion.

Dosage: Typical dosage ranges from 0.5% to 5% by weight, depending on the desired effect (e.g., slip, mold release, scratch resistance) and the base polymer. Higher dosages generally lead to more pronounced effects.

Processing Temperature: Process at typical temperatures for the base polymer. Silicone masterbatches are generally stable at high processing temperatures but prolonged exposure to very high heat should be avoided.

Ventilation: Ensure good ventilation during processing as some volatile components may be released.
