INNOVATIVE SOLUTIONS
Advantex® continuous roving is an integral part of the Silentex® system
and is designed for high thermal and corrosion resistance. The Advantex®
glass composition represents a technological advance in OCV™ Reinforcements’ commitment to provide
value-added products to our customers. The Silentex® process, combined with Advantex® continuous
roving, offers a robust solution to meet demanding acoustic requirements, increasing engine temperatures,
reduced weight and volume, reduced back pressure, and lower overall cost of silencers.
PRODUCT DESCRIPTION
The ST2070 product is OCV™ Reinforcements’ 24μm 7000 tex Single End roving based on the Advantex®
high temperature composition and is specifically engineered for use in the Silentex® process to minimize
process interruptions and ensure overall efficiency.
High density 40kg doffs of ST2070 roving are spliced together in a very precise manner to ensure package
transfer that is transparent to the Silentex® process. ST2070 is designed to ensure that the strand
consistently texturizes into 5,800 filaments to ensure that each muffler will be filled with continuous fibers,
highly effective in attenuating sound and highly resistant to blowout.
FEATURES AND PRODUCTS BENEFITS
Annealing and softening point are over 65°C (117°F) higher
than standard E glass
5 times the fiber strength of basalt wool and over 2 times the
fiber strength of E glass needle felts
Nearly 3 times more resistant to degradation due to corrosive
fluids found in typical exhausts than standard E glass
High linear density of 7000 tex
Able to withstand increasing exhaust temperatures
Stainless steel wool is not typically required to protect the fiber from the
exhaust gas
Fibers will remain continuous and resist blowout in the exhaust
Fiber strength will be retained even under the most corrosive conditions
in the exhaust
Extremely high process efficiency
Typical direct fill rates as fast as 52g/s/nozzle
Enabling smoother and more stable process for equal cycle time
compared to 4800TEX.
Narrow and consistent fiber diameter distribution
Does not contain unfiberized beads like most basalt wool
Consistent acoustic absorption
Fibers not respirable into the deep lung
Fill density can often be reduced over basalt preforms or needle felt
Excellent processability in the Silentex machines
Maintains high production efficiency
Excellent strand texturization
Minimal fuzz generation
Large 40kg doffs with only 17 splices per pallet
Very few doff transfers during filling operations
Fairly high package density: approximately 700kg per pallet
Reduces floor space compared to ready texturized materials
