The part of the ore that has no use value or cannot be used is called gangue. For example, tungsten ore is mostly formed in the quartz vein, and this quartz vein is called gangue.
The rock around the ore body is called a surrounding rock. The surrounding rock in the upper part of the ore body is called the surrounding rock or the top plate; the surrounding rock in the lower part of the ore body is called the surrounding rock or the chassis, and the rock sandwiched in the ore body is called the stone.
The surrounding rock and stone of the ore body are called waste rock, and the concept of waste rock and ore is relative. The rock with no industrial grade collected in the mining process is called waste rock.

Chlorinated Polyethylene

CPE Chlorinated Polyethylene 135A CAS 63231-66-3

Chemical and Physical Properties:

Product Name : Chlorinated Polyethylene

Molecular Formula: CH2-CHCl-CH2-CH2 n

CAS No.:63231-66-3

Production description:

Chlorinated polyvinyl chloride (CPE) is a saturated polymer material with a white powder appearance, non-toxic and odorless, and has excellent weather resistance, ozone resistance, oil resistance, flame retardancy and coloring properties, chemical resistance and aging resistance, Good toughness (still flexibility at -30°C).


CPE is a kind of crystalized white fine particle elastomer with good softness, hydrogen atomsare in special high density polyethylene replaced by chlorine atoms. Low brittle temperature, weather resistance, aging resistance make it impact and additive

modifier.

Application:

CPE135A Have excellent toughness, weather resistance, oil resistance, flame retardant, coloring resistance, chemical and other properties, is compatible with plastics, rubber, excellent filling properties. Depending on the product performance. widely used in rigid PVC products, such as PVC profile, pipe, pipe fittings, sheet and wire etc.
