Solve High Friction and Cable Installation Challenges in Optical Fiber Ducts and Pipes
Reduce Friction, Improve Cable Blowing Distance, and Enable Permanent Inner Lubrication with Proven SILIKE Silicone Masterbatch Technology
The fiber duct and utilities cable duct market is expanding rapidly in 2026, with the utilities cable duct segment projected to grow at a 14.8% CAGR through 2033. Growth is driven by 5G expansion, smart city development, and underground utility upgrades to build stronger, more secure infrastructure. However, conventional HDPE telecom ducts and industrial pipe systems still face common challenges such as high internal friction, limited cable blowing distance, difficult cable replacement, surface defects, and unstable production efficiency. These issues can increase installation costs, reduce long-term network performance, and cause maintenance downtime.
To help manufacturers overcome these challenges, SILIKE’s LYSI series silicone masterbatch (siloxane-based processing aids for modified plastics) provides an efficient, application-focused solution through durable lubrication technology and optimized extrusion performance, improving processing efficiency, pipe quality, and cable installation performance.
These SILIKE silicone-based additives are designed to lower the coefficient of friction (COF), thereby enabling smoother cable blowing, easier installation, and extended blowing distances. In HDPE telecom duct applications, the static COF has been observed to decrease from 0.21–0.22 to 0.12–0.13, while the dynamic COF can be reduced to as low as 0.05–0.06 under specific conditions.
SILIKE Silicone Masterbatch, as a plastic additive and polymer modifier, delivers lower extruder torque, reduced die build-up, coefficient of friction, improved melt flow characteristics, enhanced surface smoothness, and more stable output rates. It maintains long-term lubrication performance without peeling, separation, or visible residue.
The SILIKE Silicone Masterbatch LYSI series includes a range of processing lubricant agents for pipe extrusion, cable conduit production, and specialty duct systems, suitable for:
● PLB HDPE Telecom Ducts
● Telecommunication Ducts

★★★★★
Silicone Masterbatch LYSI-404: Improved cable blowing in long-distance telecom ducts
"We are producing micro-ducts for telecom use, and SILIKE has been quite reliable for us, both in material performance and technical support.
After we started using Silicone Masterbatch LYSI-404 in the inner layer of HDPE ducts, the surface became smoother. During cable blowing, we could feel less resistance, and the blowing distance improved compared to before.
In some cases, the installation team also reported it was easier to push through longer sections without extra effort."

LYSI-04N Silicone Masterbatch: More stable extrusion in HDPE microduct production
"We mainly produce HDPE microducts for outdoor fiber networks. One issue we always had was keeping the inner wall consistent, especially for small-diameter and multi-branch designs.
Even small changes in formulation would sometimes affect the surface, and then cable blowing in the field would not be stable.
After using Silicone Masterbatch LYSI-04N, the extrusion process became more stable. The inner surface also looked smoother. We did not have to adjust much in production after that, which helped a lot.
It also worked well with our existing HDPE blend, no real processing issues."

Silicone Masterbatch LYSI-401: Better wear resistance in large mining pipes
"For large diameter HDPE pipes used in mining, abrasion during handling and installation has always been a problem for us.
Also, sometimes we had issues with stable extrusion pressure, which affected dimensional control.
After adding Silicone Masterbatch LYSI-401, the extrusion felt easier to run. Die pressure went down, and the pipe surface seemed more resistant to scratches.
Overall, the pipes feel more stable in production and hold up better in use."
