286 The Science and Technology of Rubber FIGURE 6.1 Elastic recovery of natural rubber following imposition of a strain for the indicated time period. The initial recovery is reduced by maintaining the material in the stretched condition, but the recovery at longer times is unaffected (Mooney, 1936).
Silicone Specifications There are many variations of medical-grade silicone gumstock — also referred to as HCR (high consistency rubber). You must specify the right one in order for your silicone extrusion to function properly at the point of care.

Polymer Extrusion Process. The process of polymer extrusion involves taking raw materials and creating a product that can be formed into a unique profile of a variety of lengths, shapes and colors. The profiles are highly customizable and can be made from almost any type of rubber. There are two processes for rubber extrusion; continuous in-line cure and off-line cure.
of how the extrusion process interacts with the polymer. This basic understanding will help in troubleshooting situations where the problem is the effect of the extru-sion process on the stability of the polymer being extruded. The physical properties that are important to polymer processing are presented in Chapters3 and 4.
Extruded rubber products will differ from molded rubber products based on the process where extruded parts are forced through a die of the required cross section under pressure of an extruder. Often extruded products are unvulcanized prior to being extruded, leaving the rubber in a soft and pliable state post extrusion.

during stretching and recoil are needed, rubber and elastomers are ideal materials. An elastomer can be stretched to many times its original length yet bounce back without permanent deformation. Some rubber and elastomer products are quite economical. One of the popular elastomers for many consumer products, such as toys has been plasticized PVC.

The rubber industry bases the formula's on 100 parts of rubber. This formula was taken out of the patent literature. The styrene butadiene rubber we use is a Duradene from Firestone Polymer. These are usually oil extended and are specified by viscosity, styrene content, and vinyl groups. The high cis butadiene rubber is from Lanxess.

Hot Melt Extrusion Hot melt extrusion (HME) is the process of applying heat and pressure to melt a polymer and force it though an orifice in a continuous process. HME is a well known process, developed to produce polymer products of uni-form shape and density, and its industrial application dates back to the 1930's1. It is one of the
Rubber Extrusions NATURAL RUBBER GENERAL DESCRIPTION: Crude natural rubber is found in the juices of many plants (shrubs, vines, and trees), the principal of which is the Hevea Brasiliensis tree, native to Brazil. After the latex is processed, natural rubber becomes an elastomer with excellent mechanical properties.
Four roll calenders can have a vertical. Typical examples of extruded rubber parts are profiles. This aids the rubber extruded profiles to maintain its shape and acquire necessary physical properties. The rubber industry normally uses three or four rolls and occasionally for rough gauge sheeting. by adjusting the distance apart of the rolls.
