Case# 025: recycled HDPE bottles (blow mold), TK additive helps to solve production problem




plastic gallon drums

Resin Type:

80% recycled HDPE with 20% calpet (CaCO3 MB)


blow mold

Filler Type

calpet (CaCO3 MB)

Customer concerns:

customer intends to reduce cost by using as much recycled resin and/or calpet as possible, but disappointedly ends up with either defective bottles or blow mold machine completely shut down.

Test Result

1. by adding 0.5% of TK-1 in their current resin formulation (i.e. 80% recycled HDPE and 20% calpet); both bottle quality and machine problem has been significantly improved or eliminated.
2. due to commercial secret consideration, customer is not willing to disclose more statistical data such as production yield and drop test - mechanical strength, etc.
