Semireinforcing furnace

GPF = general purpose furnace SRF = semireinforcing furnace MT = medium thermal HS = high structure LS = low structure LM = low modulus. Dibutyl phthalate [84-74-2] absorption.

Carbon blacks are usually used as fillers. The semireinforcing types, such as FEF (fast extrusion furnace) and SRF (semireinforcing furnace), give the best performance. To lower the cost and improve the processability of light colored... 

Occasionally a combination of clay with some semireinforcing furnace blacks can be used in place of thermal black. However, other properties are affected. 

Carbon blacks are arbitrarily classified into reinforcing, semireinforcing, and extender blacks. The furnace blacks from NlOO through N400 are... 

A type of carbon black produced by burning natural gas or oil in a large furnace with a supply of air much lower than that required for complete combustion. The main types are super abrasion (SAF), intermediate super abrasion (TSAF), high abrasion (HAF), fast extrusion (FEF), general purpose (GPF), conductive (CF) and semireinforcing (SRF). 

Most furnace black reactors are arranged horizontally. They can be up to 18 m long with an outer diameter of up to 2 m. Some vertical reactors are used especially for the manufacture of certain semireinforcing blacks [4.12] (Fig. 51). For further reactors, see [4.13].
