However, many technologists use the term "compound" in the sense of a mixture. In rubber technology, a compound is a composition obtained by adding to an elastomer substance known as compounding ingredients and blending to produce a homogeneous mixture or mix. Other terms for this unvulcanised mix are mixing, stock, blend, or quality.

A milky, product excreted from the latex canals of a variety of plant species that contain cauotchouc. Latex is composed of 25-35% caoutchouc, 60-75% water, 2% protein, 2% resin, 1.5% sugar & 1% ash. RUBBER is made by the removal of water from latex. (From Concise Encyclopedia Biochemistry and Molecular Biology, 3rd ed).

where M c is the average molecular weight of the rubber between the crosslinks, V r is the volume fraction of the equilibrium swollen rubber, χ is the Flory–Huggins polymer-solvent interaction parameter, vs. (cm 3 mol −1) represents the molar volume of the solvent used and ρ r (g cm −3) is the density of rubber .
(HMT) Cohedur H 30 DCBS 1.1 The cure package is composed of a slow accelerator (DCBS, or TBSI) with a high level of sulfur for PVI 0.2 improving the bond strength between the rubber and IS OT 20 2.2 brass layer. A typical formulation is shown in Table 42.

Jan 23, 1991· Natural Rubber: (NR) 100 phr--Most belt skims employ an all NR compound although some skims utilize a blend of NR and Polybutadiene Rubber (BR). BR and/or NR is usually the major component of the blend. As is conventional, the amount of rubber is reported as 100 parts, and all ingredients are reported as parts per hundred of rubber, (phr) by
Elemental sulfur is the predominant vulcanizing agent for general-purpose rubbers. It is used in combination with one or more accelerators and an activator system comprising zinc oxide and a fatty acid (normally stearic acid). The most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithocarbamates and guanidines.
