Description

Material Notes:
MPP-D80B has a high load-bearing property at hardness 80 D Durometer. This material has a relatively slow curing pattern. Whereas many polyurethane formulations of this hardness cure very fast thus are very difficult to hand-batch or to cast a larger part. MPP-D80B gives a long pot-life for ease of process. The combination of there properties makes this material ideal for prototyping molding to imitate hard plastic parts. The material will cure at room temperature. However, processing at a slightly elevated temperature (110 – 120 ºF) will allow faster demolding time to achieve a better production rate. This material can be processed at either room temperature or using heat. Note: Heat distortion temperature of this material is relatively low and it is not suitable for application which require load bearing property at an elevated temperature range.Information provided by Northstar Polymers.
