PROPERTIES
:
|
- CPVC has an HDS (hydraulic design stress)
list at 180°f or approximately 40°f
above that of other rigid vinyl
thermoplastics.
- CPVC has a tensile strength of more than 2000
psi at 212°f
- CPVC is essentially immune to salvation or direct chemical attack by virtually all
inorganic reagents, aliphatic
hydrocarbons and alcohols.

CASTINGS |
|
|
|
PROCESS
DEFINED : |
|
castings made by pouring molten metal under a gravity
head into molds prepared by packing molding sand around a suitable pattern. |
|
MATERIALS : |
| principally
iron, magnesium, aluminum, & copper
alloys. |
|
RATE OF
PRODUCTION : |
| low
not a high production process. |
|
SIZE &
WEIGHT OF PARTS : |
| medium
to very large. |
|
STRENGTH OF
PARTS : |
| less
than die casting & permanent mold
castings. |
|
WALL
THICKNESS : |
| must
be heavier than die casting & permanent
mold casting can be cast in section 1ft. or
more. |
|
