RIM Molding PUR Materials
Determining which type of polyurethane pur material system will work best for an application will depend on the degree of rigidity is needed for the application. The degree of righty will place it one of two categories; a rigid polyurethane or an elastomeric.
Within these two categories (rigid and elastomeric) there are three (3) classifications of polyurethane (PUR) material systems; Solid PUR, Foamed PUR and structural composite PUR.
Galaxy3DM molds PUR material systems. Polyurethane is the material used for all of our part applications. Virtually no other material combines aesthetics, ergonomics and function in such an ideal form.
A rigid PUR material system has a higher flexural modulus and degree of hardness. Typical properties associated with rigid polyurethanes are good chemical resistance, electrical properties and acoustical thermal insulation.
An elastomeric polyurethane PUR material system is usually used in applications needing superior impact strength. They have good toughness and dimensional stability under a variety of temperature ranges (to -30 degrees Fahrenheit). Even under these temperature loads, the elastomeric polyurethanes retain excellent physical properties such as excellent abrasion, corrosion resistance and wear resistance.
Within these two categories (rigid and elastomeric) there are three (3) classifications of polyurethane (PUR) material systems; Solid PUR, Foamed PUR and structural composite PUR.
Solid Polyurethane Systems
Solid polyurethane pur systems don’t include blowing agents resulting in a solid rigid or elastomeric solid plastic. These elastomeric systems are typically used for automotive trims, fascias, bumpers and other parts in the construction, automotive, recreational and agricultural industries. The solid rigid systems are usually used to mold thin walled parts (3-6mm) resulting in applications such as business machine covers, medical device covers, large format parts and other parts similar in design and use as typical injection molded parts.
Structural Composite PUR Systems
These polyurethane systems are foamed systems and can variable wall sections. These systems have extremely high stiffness and high impact strength due to additives of glass or glass mats in the molding process. Typical applications include panels, shelves, load bearing parts and housings.
Foamed Polyurethane Systems
- Higher density skins with lower density microcellular cores in a sandwich like composition
- Ability to design parts with variable wall sections (up to 2”) without sink or distortion in the part
- Useful for load bearing applications
- Allows designers to integrate the structure of a housing with the aesthetic needs of the part in a single part (sometimes eliminating the need for sheet metal sub assemblies for mounting the covers to)
- Applications include but are not limited to business machine covers, medical device enclosures and housings, device bezels, ski’s, car spoilers and many more.
