Safely packed in cardboard carton (dimensions: 1320 x 320 x 160 / 1320 x 160 x 160 [mm]) with cushioning
Flexible multipurpose Penntube heat-shrink tubing for bonding electrical cable
Can be used for protective coating of objects Provides superior resistance to heat and chemicals Can be used for a wide variety of applications, including insulation protection
Fluororesin heat-shrink tubing, made with 100% high-quality made-in-Japan fluororesin. By simply coating an object, it grants heat resistance, insulation, anti-adhesiveness, and viscosity. Simple protection from and reinforcement against the external environment, with chemical resistance
and anti-staining properties. Demonstrates its abilities, including the ability to bind cables and harnesses
as well as heat resistance and insulation protection, in a wide range of applications in numerous fields,
such as aircraft, electronics, cars, appliances, and more.
Penntube SMT series The most widely-used, all-purpose series, with outstanding workability and value. Shrinkage rate: 25% Continuous use temperature: 200°C Shrinkage temperature: 120°C
The standard length is 1.2 m. The standard color is translucent. Products with a packing unit of 30 m can have a length of over 10 m, with the joints together.
Penntube SST series With a larger shrinkage rate than the SMT series, this series is compatible with a variety of objects. Shrinkage rate: 40% Continuous use temperature: 200°C Shrinkage temperature: 140°C
The standard length is 1.2m. The standard color is transparent. Products with a packing unit of 30 m can have a length of over 10 m, with the joints together.
Penntube PFA series Outstanding mechanical properties in high temperatures. The continuous use temperature surpasses that of the other series. Shrinkage rate: 25% Continuous use temperature: 260°C Shrinkage temperature: 140°C
The standard length is 1.2 m. The standard color is transparent.
Shrinkage begins at about 80°C, and it shrinks almost completely at the shrinkage temperature. The temperature for complete shrinkage is 200°C. It shrinks at high temperatures, so please store it at 40°C or below. If you are unsure about what size to select, please consult with us.
If you tell us the dimensions of the object you intend to coat, we will select the optimal size. We can also provide samples.

Exhibited at M-Tech, the mechanical components and materials technology expo, in June 2016. This product will be shown at exhibitions, and we will be making many proposals.
We have brought in much of the latest equipment.
We have established our own in-house standards, and carry out dimensional measurements and tests of all kinds to ensure high quality. All of our products are inspected visually, so that we can provide reliable quality to you.
Since obtaining ISO 9001 and ISO 14001 certification in 2005, we have built a track record of applying this knowledge for over 10 years. We are scheduled to become compliant with the latest standards at the start of 2017.
We unsparingly offer the experience and know-how we have accumulated as only a specialized manufacturer of fluororesin tubing can.
We also offer Pennchem CT, flexible tubing suitable for space-saving internal piping.
