Molded Dimensions is Essential Business: Open and Shipping Product.

The Coronavirus situation continues to change daily. Here are the updates from Molded Dimensions.

1) Employees: We are initiating work from home for positions where this is possible. Our manufacturing employees, and other essential staff, in Wisconsin continue to report for work and production continues as normal. In addition to regular workplace sanitizing, we continue to provide ways to social distance ourselves and reduce cross-contamination between departments and facilities.

2) Raw Material Supply: We continue to monitor our supply base to assure our raw material stock is available to provide uninterrupted supply for our customers.

3) Production Commitment: Our manufacturing employees are considered "Essential Critical Infrastructure Workers." We do not plan to shut down manufacturing and shipping unless required to do so by governmental restrictions.

Best regards,
Patrick Roddy

PU Design Suggestions

April 29, 2016

urethanedesign1c2We take pride in designing the best possible polyurethanes the industry has to offer, and that is due to the strict guidelines and standards we set for our self.

Sharp Edges
Sharp edges or corners, externally or within the polyurethane part, should be avoided, particularly where the polyurethane is stressed.

Polyurethane Has Many Unique and Desirable Properties as a Thermoset Elastomer

January 15, 2016

Material Properties
Millable urethane rubber is available in hardnesses ranging from approximately 30A-90A.  While castable urethanes cover this range, they also can be formulated slightly lower and significantly higher.  In the range of 30A-70A, millable urethane rubber has superior physical properties to castable urethane, primarily tensile and abrasion resistance.  At these lower hardnesses, millable urethane takes advantage of reinforcing fillers to build strength while castable urethanes often need to be plasticized to reach durometer readings below 55A.  Once the hardness gets above 70A, and up to 75D, the tensile values of castable urethane start to catch up and surpass millable urethane.  This can also translate into increased load bearing properties and superior abrasion resistance with castable urethane.

MDI Chemist Explains Updates in Polyurethane Industry

July 31, 2015

Written By: Tony Lukas, Chemist Molded Dimensions Inc

screen-shot-2015-07-31-at-9-33-35-amPolyurethane suppliers and processors are continually looking to develop new materials and applications to take advantage of the unique properties of urethane.  One advantage that urethane has over rubber is much higher abrasion resistance.  This has historically been particularly true as the hardness reaches Shore 80A and above.  Although materials of softer hardness have long been available, the physical properties and abrasion resistance has not been a good as rubber in the 50A-70A range.  New developments are allowing for both polyether and polyester based materials that are great improvements over currently available urethanes and even better than natural rubber and SBR.  Typical applications for these types of materials would be in systems with heavy flow of particulate containing liquids or slurries.
