Introduction

Coats has been a pioneer in the industrial thread business for over 250 years. By listening to our customers and adapting to new technology and practices, Coats has been able to establish itself as a global leader in high performance sewing threads and engineered yarns.

Coats has also developed cutting edge products and services for the wire & cable industry, specifically in the area of fibre optic cable manufacturing. Offering a wide range of material substrates, our products are used as ripcords, binder yarns, marker yarns and for dry water blocking.

From the water swellable Ultrabloc S/SC, to the ultra-low shrink Gral Binder LS, Coats is dedicated to providing our customers with solution-driven products. By doing so Coats becomes your partner, one that not only provides quality products, but also global service and peace of mind.

Inside the Cable

Ripcords

Ripcord

Brand	Product	Description
	Protos Ripcord PF	Continuous filament, twisted, para-aramid yarn designed specifically for armoured cable ripcord applications. The unique protective film (PF) coating is highly abrasion resistant and proven to help reduce ripcord size.
	Gral Ripcord PF	Polyester based, continuous filament yarn is best used for fibre optic cable ripcord applications. The unique protective film (PF) coating is highly abrasion resistant, has greater cutting modulus, and is proven to help reduce ripcord size.

Application

• Ripcord for armoured and non-armoured cables.

Available Substrates

• Polyester
• Aramids

Binders

"Binders"

Brand	Product	Description
	Gral Binder	Multi-filament polyester yarn that is used in designs that call for standard low shrink (2%) binders. Packages are consistent in length, can withstand high stranding speeds and are available in one end and two end put ups.
	Gral Binder LS	Multi-filament polyester yarn that is ultra-low shrink (0.4%), offers high tensile strength and will not indent buffer tubes which can cause a defect in the cable and disrupt the stranding operation. Packages are available in one end and two end put ups.
	Protos Binder	Multi-filament para-aramid yarn that is used as a binder in loose tube designs requiring extra low shrink binders. Packages can be stranded in multiple directions, require less ends and are very light. Available with wicking or non-wicking.

Application

• Binders for loose tube telecommunication cables to prevent damage to buffer tubes. Ideal for high speed binder applications (up to 120m/min).

Available Substrates

• Polyester
• Aramids

Strength Members

"Strength Members"

Brand	Product	Description
	Protos SM	100% para-aramid fibre that is stronger than steel and offers enhanced tensile strength as well as stability to any fibre optic cable.
	Glasmo SM VO	Oval shaped glass fibre strength member engineered yarn for use in telecommunication cables that provides linear strength and stability and can be used to promote adhesion between the glass fibre components and cable sheath without the need of an IR pre-heating process. The improved strength of the glass fibre means that cables can be redesigned to be smaller in size, saving cost.
	Glasmo SM VF	Flat, flexible glass fibre strength member yarn for use in telecommunication cables that provides linear strength and stability as well as rodent protection.
	Glasmo Ultrabloc VFF	Multi-functional, flat glass fibre strength member yarn that provides linear strength and stability as well as rodent protection and is ideal for dry blocking in fibre optic cables for any application requiring no mess processing.
	Glasmo Ultrabloc VRO	Oval shaped, multi-functional glass fibre strength member yarn for use in telecommunication cables that provides linear strength and stability, and is ideal for dry blocking in fibre optic cables for any application requiring no mess processing.

Application

• Strength members for drop wire cables including copper, fibre optic, shielded and coaxial cables

Available Substrates

• Fibreglass
• Aramids

Water Blocks

"Water Blocks"

Brand	Product	Description
	Protos Ultrabloc VLF	Standard modulus coated aramid yarn that is water swellable and used in binder applications. The super absorbent polymer coating is applied to the yarn which enables it to provide 2-3 times better water absorption than competitors.
	Protos Ultrabloc LF	Water swellable coated aramid for use in telecommunication cables. Available in two different types, Type A is a standard modulus that is mainly used as a water swellable binder in general telecommunication cables, and Type B is a high modulus that is utilized as a water swellable strength member for ADSS cables. Both types have some of the lowest dusting and shedding in the industry that helps reduce machine downtime and improve cleanliness and safety during the cable manufacturing process.
	Ultrabloc S/SC	Water swellable yarn that is ideal for dry blocking in fibre optic cables for any application requiring no mess processing such as dry buffer tube blocking or dry blocking around central strength members. A pure spun super-absorbent polymer thread, the polyester core adds strength and temperature stability which are important to minimise potential impact on attenuation of optical fibres especially for inside tubes as the yarns lay adjacent to the fibres. *Can also be used for salt and sea water blocking.
	Ultrabloc SH	Very high absorbing, water swellable yarn / filler, ideal for dry blocking in cables that require extra water blocking such as inside ribbon or unitube fibre optic cables, copper communication cables, and medium to high voltage energy cables. The yarn is a pure spun super-absorbent polymer with a polyester wrap which appears “fluffy” and very soft allowing them to easily change form and fill empty spaces in all types of cables. *Can also be used for salt and sea water blocking.
	Dabond Ultrabloc L	Continuous filament, high tenacity, polyester coated with an extremely smooth super absorbent water swellable finish. This is an excellent general purpose water blocking material and is appropriate for a wide variety of uses in fibre optic cables where high absorbency is needed.

Application

• Water blocking components for outside plant cable applications

Available Substrates

• Polyester
• Aramids
• Fibreglass
• SAP
