Features of Excellen™ VL

1. Flexibility

Excellen™ VL shows excellent flexibility due to its low density and low crystallinity

2. Heat resistance

Excellen™ VL has broad chemical composition distribution and also possesses high melting point component.

3. Filler acceptability

Excellen™ VL has excellent filler acceptability due to its high content of amorphous phase.

4. Good processability

Excellen™ VL has good processability due to its broad molecular weight distribution.

Features of Excellen™ FX

1. Impact resistance

Excellen™ FX is a good modifier for improving the impact resistance of LLDPE due to its flexibility.

2. Pinhole resistance

Excellen™ FX improves pinhole resistance when mixed with LLDPE due to its flexibility and high tensile strength.
