Booming prices for resins, the building blocks for plastic, have already helped drive up the cost of making everyday products such as toys, bottles and face masks.

Now the fossil-fuel-derived ingredient could get even more expensive as Russia’s attack on Ukraine raises the risk of higher oil prices, potentially trickling down to what consumers pay for household and personal care products. Brent crude had already risen almost 48% in the last year.

Efficient, Profitable Plastics Extrusion Begins with Materials Knowledge

All plastics have additives — some obvious, some invisible

First of all, no plastic is 100% pure when it goes into the extruder. All of them have additives — some are obvious, like colorants, and some are invisible, like light stabilizers that keep the Sun’s ultraviolet rays from breaking the molecules and discoloring or weakening the plastic.

HMM — how much matters — is my favorite acronym. I squirm when I hear the words “in it,” as in “it has sugar in it” or “there’s BPA in it.” I want to scream, “How much is in it?” but usually I don’t. Often the speaker wants/needs to avoid dealing with the actual amount. Additives are prime examples: We can’t know a compound is adequately protected from sunlight degradation (UV) without knowing what the additive is, how uniformly it’s mixed, and how much of it is in it.
