Case# 023: PP blades (plate), TK additive helps to improve productivity and quality




PP blades (plate)  manufacturer for automobile interior compartment and panel

Resin Type:




Filler Type


Customer concerns:

1. productivity improvement and cost reduction
2. better surface finish

Test Brief:

Control Cell

customer has been trying used different formulations:
1. PP compound of PP 50% homopolymer + 50% copolymer (exact formulation undisclosed)
2. 70% PP + 30% talc

Test Cell

a. Polypropylene copolymer (MFI 0.8); 1334,4 kg; and
b. Talc, 660 kg; and
c. TK-1, 5.6 kg (approx. 0.28% by weight)
Total PP compound 2000 kg; this special compound was provided by a masterbatch manufacturer (Note: this masterbatch manufacturer reported 9.2% production throughput increase after TK applied comparing with the previous production output of 70% PP + 30% talc without TK
Test Result:


The hourly production throughput can be raised from 400 kgs (Control Cell) to 478 kgs (Test Cell); almost 20% productivity improvement. (the extruded PP blade is 2-meter wide and 7-mm thick)
2. The extruder is a model with the microprocessor control. The extruder temperature was able to lowered from 210o C to 195o C. The effect of TK upon PP resin is obvious and preferred. Operators noticed that TK provides better agglomeration between resin and filler; TK is also a good lubricant and a good heat transfer media
3. no visible surface imperfection and glossier finish
4. passed quality inspection at the automobile compartment manufacturer
Major Benefits:

1. increase productivity
2. better product's cosmetic quality
3. reduce electricity power bill
