“Vinyl or PVC” :
Vinyl is soft, flexible, and economical. It is the most common plastic extruded over steel cable. It offers
good weathering resistance and outstanding resistance to ultra violet rays of the sun which degrades
many plastics over time. Vinyl has good resistance to water and some resistance to acids and alkalies.
Since it is softer than other plastics, vinyl is not always the best choice when abrasion is a factor, such
as over pulleys.
Vinyl grades are defined by the durometer which is a measure of hardness. For cable
extrusion an 80 to 90 durometer vinyl is commonly used. The higher the durometer the harder the PVC.
Under normal conditions, vinyl has a general operating temperature range of ‑30°F (‑35°C) to +180°F
(+80°C). Color can be easily added to vinyl to achieve almost any shade desired. From fluorescent pink
to olive green, we can match a color to suit your needs. Natural vinyl is very clear in color.
Vinyl complies with Military Specification 631, Type F, Form U, Grade A, Class 2.
Nylon Type 6:
We like to think of Type 6 grade nylon as our “general purpose” nylon. This type
is suitable for most applications and is very cost efficient. We work closely with our nylon suppliers
to offer our customers a nylon that is hard and durable but also one that is easy to
strip for assembling cable fittings. In most cases, a plasticizer has been added to these two
types to reduce the stiffness in the nylon. Type 6 nylon offers good resistance to abrasion
and most chemicals. This nylon has a general operating temperature range of ‑40°F (‑40°C)
to +200°F (+95°C). U.V. inhibitors can be added to nylon to aid in the resistance of sunlight
degradation. Natural Type 6 nylon is clear to milky white transparent in color. Color concentrates can
Nylon Type 11 :
We provide a Type 11 nylon which meets the requirements of MIL‑DTL‑83420. This
durable, high quality nylon offers good abrasion resistance when operated over pulleys. It provides
good resistance to chemicals. This nylon has a wider operating temperature range of ‑65°F (‑54°C) to
+230°F (+110°C) and reacts well in severe cold temperatures. Natural Type 11 nylon is clear transparent
in color. Color concentrates can be added.
Polyether Block Amide (Pebax):
This high quality plastic is flexible yet very durable and runs easily
over pulleys with good abrasion resistance. This plastic can withstand extremely cold temperatures
and still remain flexible. It has a general operating temperature range of ‑66°F to +150°F. In addition
to extrusion over steel cable, Pebax plastic is also used to produce such products as golf balls and ski
boots. Pebax is offered in natural or black color. Color concentrates can be added.
A lightweight, reasonably priced plastic sometimes used in place of vinyl. It has good
water and abrasion resistance and is very flexible. Its operating temperature range is narrower than
vinyl and it is not recommended for application in cold temperatures below 0°F. Ultraviolet rays of the
sun will degrade polypropylene faster than other plastics.
Available in high and low density. Polyethylene offers good resistance to a wide range
of chemicals and is unaffected by water. We offer a low density polyethylene with excellent environmental
stress cracking resistance, outdoor weatherability, and toughness. Offered mainly in natural or
There are many plastics available for extrusion onto steel cable. We have used numerous grades and
brands when specified by a customer or for a particular purpose. Please call our sales department to
discuss your needs.
