THE PROPERTIES OF SPESIN®

SPESIN® FOR CONNECTOR

SPESIN® meets all the requirements for high flow, high impact resistance and high durability required by PBT for connectors .

SPESIN® is a material that satisfies both rolling drop, fastening strength, terminal retention and high vibration durability.

It can be applied without limitation of product thickness, structure and usage.

SPESIN® FOR OPTICAL FIBER CABLE

SPESIN® is a high viscosity PBT optimized for tube extrusion.

It is a high molecular weight polymer that enables the melt viscosity to be maintained and stable in the extrusion process.

In particular, even in the case of high-speed extrusion, it is easy to secure the stability of the extrusion pressure and the outer diameter deviation. In addition, the optical fiber protection effect is outstanding.

SPESIN® FOR AUTOMOTIVE WIPER BLADE

SPESIN® achieves high mechanical strength and excellent performance as an automotive plastic wiper blade. In addition, it meets the following weather stability.

THE PROPERTIES OF SPESIN® INJECTION CONDITIONS & HANDLING PRECAUTIONS

SPESIN® FOR HEAD LAMP BEZEL

SPESIN® has high fluidity due to the thinness and light weight of complex product shapes and product thicknesses required for head-lamp bezels for direct coatings.

It also has the effect of reducing the defect rate in the coating process based on low gas release and haze characteristics.

Note: KOLON PL AS TICS has prepared this repor t based on the data obtained up to the time of writing. The figures in all tables are representative values, not quality assurance values. The figures in the table can not be used as basic data for semi-finished products and finished product designs. As product quality improves, figures in the table may change without notice.

PRE-DRYING

SPESIN® is a thermoplastic polyester material, and if it is molded in a state containing water, the property may be lowered.

If the PBT is in a moisture-absorbed state, surface quality problems may occur, including deterioration of long-term physical properties.

Therefore, pre-drying of the resin is required. It is recommended to use a dehumidifying dryer at a temperature of 100 ~ 120°C for 4 ~ 5 hours.

SPESIN® is low in moisture absorptivity compared to materials such as PA. However, there is a risk of fluctuation of injection or extrusion characteristics depending on the moisture absorption amount, and it is preferable to maintain the water content of 0.04% or less in tube extrusion or micro injection molding We recommend that you.
