Injection Molding

Millad® offers excellent solubility in high melt flow rate (MFR) PP resins. Our clarifying additives can be processed at lower temperatures without impacting optical performance, decreasing cooling times and increasing production capacity.

Thin Wall Injection Molding

Millad® expands the clarity once limited to amorphous polymers to PP, creating inter-material replacement (IMR) opportunities. Using PP can translate to resource and production savings on thin-wall injection-molded products.

Thermoforming

With Millad® clarifiers, PP can achieve clarity levels on par with polyethylene terephthalate (PET). Clarified PP offers the added benefit of heat resistance ideal for thermoformed packaging used in microwave and heated applications.
