Design Guide
This guide is intended to give design engineers the basic facts needed to begin the process of designing effective rubber seals, gaskets and weather stripping. This guide is intended as a starting point and is not intended to provide all information available on the processes of extrusion and molding. This guide will help engineers better understand what they will need to consider during the design process.
The Lauren Catalog
This catalog presents an overview of Lauren's typical products and services for customers requiring a sealing application. However, there are numerous variables involved with product design and production; therefore, it is advisable to call Lauren with specific needs so we customize a solution that is constantly on time and on budget.

Talk to an engineer
If you have a specific question about your design project, our engineer will be glad to answer it.
Physical properties of compounds
Developing the right compound (material) is a crucial step in the design process. In their original state, most rubber polymers have limited commercial value. Therefore, a compound "recipe" must be developed to enhance or add to a polymer's inherent physical and chemical characteristics, and to insure efficient molding or extruding.
Chemical properties of compounds
The range of properties that can be developed for any given polymer is limited by the material itself, and will vary within that range with compound formulation. All properties in a particular class are not found in a single compound. However, it is often possible to raise or lower some ratings to acceptable levels
through creative compounding.
Pressure Sensitive Adhesives
In many cases, the use of pressure sensitive and HATS (heat activated tape systems) adhesives can eliminate mechanical fastening systems (staples, nails or retaining clips), and the inherent problems associated with them, such as cost, weight, and breakage. PSA and HATS frequently improve productivity during the final assembly process by providing a faster, more efficient way of attaching seals and gaskets to the end product.
RMA Tolerance Tables
Standard tolerance tables for design reference
Compression set information and compression deflection test
The term compression set test is used to determine the quality of rubber compounds and their applicability to certain types of usage.
