Takeaways from a half century in the latex industry
I retired recently, but still feel contributive and expect to be so for quite a while. The expression, “If you enjoy what you do, you’ll never work a day in your life,” sums up what I believe. It helps to have a positive attitude, as well. This attitude provides resilience and sustainability in the face of uncertain outcomes. After more than 50 years in the latex industry, I would like to share a few of my takeaways from those years.

Engel launches pay per use for machine molding
ENGEL breaks new ground in injection molding machine distribution. Blazing a trail for its industry, the machine manufacturer now offers its customers a pay-per-use model on top of classical machine purchases. This helps processors to reduce their investment risk while at the same time boosting flexibility in production.

Smithers develops study on low-temperature tire rolling resistance
Tire rolling resistance is closely related to overall vehicle fuel economy or range in both ICE and electric vehicles (EVs). Currently, it is understood that rolling resistance reduction is a reliable strategy for optimizing a vehicle’s fuel economy or cruising range. Many countries, regions, and manufacturers are establishing rolling resistance targets in order to achieve greater energy savings, fulfill “green” initiatives, and reduce carbon emissions.
