Insulstretch® Magnet Wire Insulation
lnsulstretch 42HCF is a 3 mil, highly densified, thermally upgraded, creped/calendered electrical paper with
15-20 percent MD elongation. This grade exhibits very high tensile strength with precision thickness and density.
This premium magnet wire insulation is well suited for high speeds and tensions in wire wrapping operations. After the wire is wrapped, this grade will give the maximum amount of protection for small radius bends in the coil winding process. Cindus grade
42HCF has proven to be a superior creped/calendered magnet wire insulation.
lnsulstretch 32HCFis a 3 mil companion product to 42 HCF. This grade is a lower cost alternative that provides superior tear strength but reduced tensile strength. This grade also offers improved impulse characteristics because of higher density.
lnsulstretch 22HCF is a 2 mil, highly densified, thermally upgraded, creped/calendered electrical paper with 15-20 percent elongation. This grade is offered to accommodate different insulation systems that call for space saving 2 mil thickness. This grade also supplies excellent mechanical and insulating characteristics comparable to 42HCF.
The densification process at Cindus Corporation can achieve densitieswell in excess of 1.0 gmlcc to provide higher impulse strengths. Cindus can customize the above grades to varying densities by altering the finished thickness.
The thermal upgrading system used on all magnet wire grades is INSULDUR. Other upgrading systems can be furnished with appropriate quantities.
All magnet wire grades can be prepared as precision slit pads as narrow as 3/8" and as master rolls of up to 22 1/2" wide.
Thermal upgrading using alternative systems is available with appropriate quantities. Nitrogen content is varied depending on customer needs. All tests are certified to conform to specific requirements.
Expert Remarks: If the objective of these studies was to compare the Cindus and our competitors upgraded papers, it has been accomplished. Both papers are very similar in properites, although there are minor differences: The competitor crepe is stiffer than Cindus crepe. However, the stretch properties are most important only during taping. Aged insulation on the conductors do not experience tensile forces, but short circuit events exert compressive forces, and we do not have a comparative evaluation of these properties.

Insulstretch Tubes
Cindus Insulstretch Tubes are made from electrical grade creped paper, wound convolutely for maximum flexibility. Available in a number of different sizes and wall thicknesses, Insulstretch Tubes are tested for conformance to industry standards.
Seams
Seams made of specialized adhesive are strong and durable, designed to resist splitting while retaining optimum flexibility. Power Factor stability is insured by the chemical nature of the adhesive and the use of only the amount necessary to properly fabricate the tubes.
Performance
Insulstretch Tubes are designed for maximum performance in all applications. Contact us at 1-800-543-4691 with your requirements.
Insulstretch Hand Tape
These products are used for a variety of end uses from automotive starter motors and electric motors to static rings, high voltage cable and coil separation sheets. The base paper used is either 3 or 5 mil high density or low density stock. The stretch and thickness is varied to meet the needs of the end user. Thermal upgrading to INSULDUR, GETP or other systems is available with appropriate quantities. Laminate grades of 51OH are available for specific needs.
High Density: 55H, 55HC, 510H, 510HC, 35H, 35HC, 310H, 310HC
Low Density: 35,310,55,510, 510C.
Automotive starter motors, electric motors, static rings, high voltage cable wrap and other hand taping applications have used Cindus Insulstretch products. These grades are also used for coil separation in the coil winding process. Either high or low density grades can be calendered to precise thicknesses.
X-Crepe has also been used in starter motor applications where greater flexibility is needed for convolute wire wraps that must endure extreme radius bending. Sample grades of X-Crepe are available upon request.
