HFFR Cable
HFFR Cable Suppliers
HFFR (Halogen Free, Flame Retardant) polyolefin compounds for cable insulation mass can be produced best with HFFR cable compounding systems. Polyolefin’s have outstanding insulation properties, but are so easily combustible that they have to be made flame-retardant accordingly. We are leading HFFR cable Suppliers in Kolkata, West Bengal, Bihar, Odisha, Jharkhand & all over India Market.
High energy savings combined with safety and eco-friendliness Built for the protection of human safety, HFFR cables provide you with the security and are safe, reliable, fire retardant, and flame retardant; lead free and non-toxic in composition. Also, they ensure that in the unlikely event of a fire, the cables will retard its spread. HFFR is practically halogen free & ensures that people trapped in fire can breathe easy facilitating better chances of their rescue. AMCO Electricals has consistently led the way by innovation and technological advancements. Keeping the environment in mind, we believe in producing eco-friendly wires that solve the required purposes without any harm. For a device to function properly, it is mandatory that the connections are strong and the wires do their job perfectly. At AMCO Electricals, we have made a note of the same and produce efficient wires that never let you down. All your electrical products are safe and will work just fine with the AMCO Electricals Wires. With the promise to deliver the best in Kolkata market.
In Europe the legal regulations mentioned above demand the use of HFFR and Zero halogen cable compounds for public facilities and installations including buildings, tunnels and transportation. In future these regulations are also expected to apply in India. In plant and engineering construction, the use of HFFR and Zero halogen cable compounds for complex and safety-relevant installations such as power stations, industrial, chemical and pharmaceutical plants, data centres, etc. has prevailed in order to minimize risks and consequential damages. In order to meet the demanding requirements for flame retardant properties, it is generally necessary to add 50-70 % of the appropriate fillers. For some applications, as much as 80% is needed. This has challenging consequences with regard to the other physical properties, as well as the compounding process, cable manufacturing, and end use. Formulations are therefore preferred with PE-copolymers, which enable higher filler absorption. Coupling and/or cross-linking systems are integrated in order to attain the required mechanical and application-relevant properties. The HFFR cable and Zero halogen cable compounding technology of the BUSS compounding systems overcomes these challenges from the production process side.
Specific benefits:
Compounding and pressure build-up optimized in two independent steps
Mixing on the BUSS Kneader and pressure build-up in the discharge unit are separated to enable the efficient optimization of both steps. This compounding system allows mixing at low pressure and temperature as well as optimized pelletizing, while maintaining temperature control at all times.
Uniform, moderate shear rates
uniformly moderate shear rates allow controlled mixing in the compounder at lower temperatures while imparting only the required shear for the task at hand. The narrow shear rate distribution compared to alternative systems ensures uniform shear histories for every individual particle. This results in high quality compounding with reduced energy input.
High filler loadings
Filler loadings of up to 90% are possible with BUSS compounder technology owing to partitioning into two or three feeder openings, the use of feed-in vessels such as side-feed screws, separate gravimetric feeding of filler, removal of trapped air by back venting, and excellent conveying efficiency. The moderate shear rates allow perfect handling of the highest viscosities at such high loadings.
Intensive mixing at low specific energy input
BUSS multiple-flight compounders of the latest generation achieve better mixing at 15-40% lower overall specific energy input. This is because of an increased number of mixing cycles according to the needs of each individual process section. The energy for melting and mixing is provided almost entirely mechanically and optimally dissipated according to the imparted shear rates.
Precise temperature control
The Buss Kneader within the silane cable compounding technology and system permits precise temperature control owing to controlled energy input and uniform, moderate shear rates, along with precise temperature monitoring by thermocouples mounted at relevant positions along the barrel in hollow-bored kneading pins surrounded by polymer.
