Grade Lineup

The following shows the features of the major grades of SUMIKASUPER LCP. When selecting a grade, first select the series based on the heat resistance required for the application.

(1) E5000 series

The E5000 series has the highest level of heat resistance among super engineering plastics. Use this when ultra-high heat resistance is especially needed with lead-free solder (dipping) at up to 400°C. However, it has super heat resistance, so the molding processing temperature is also high. Therefore, molding machines with high temperature specifications are needed along with regular maintenance.

(2) E4000 series

The E4000 series is a grade with excellent moldability and good heat resistance. Use this when heat resistance is needed up to 380°C with lead-free solder (dipping) such as for bobbins and relay cases. Since the standard molding temperature is 380°C, molding is possible using standard molding machines.

(3) E6000 series, E6000HF series, SV6000 series, and SV6000HF series

Our standard grades are the E6000 series, E6000HF series, SV6000 series, and SV6000HF series. These are well-balanced grades that have good mechanical properties and dimensional stability comparable to general-purpose engineering plastics, as well as high moldability, in addition to heat resistance capable of withstanding surface mounting (SMT) of electronic components. These can be used for a wide range of purposes. For applications requiring high dimensional stability and high moldability, select the E6000HF or SV6000HF series, which have excellent flowability.

(4) SZ series, SR series

The SZ series and SR series are special high-performance compound series with special functionality over existing grades. These are developed from LCP resin for specific applications such as connectors and LEDs. For applications requiring high flowability such as ultra-small parts where the flowability with E6000HF and SV6000HF is insufficient, select SZ6505HF or SR2506, which have the highest level of flowability among LCPs.

How to Select Each Grade

(1) Glass fiber reinforced grade

This grade of LCP reinforced with glass fiber has excellent mechanical strength and heat resistance. Characteristics such as mechanical strength, heat resistance, dimensional stability, and moldability change according to the length and amount of glass fiber filler.

• When mechanical strength and dimensional stability are needed, select the grades indicated with “L” such as E5008L, E4006L, E6006L, and E6007LHF that use chopped glass fiber (long glass fiber). When high strength is needed, consider SR1009 and SR1009L from the SR series with the highest level of mechanical strength among LCPs.
• When high heat resistance and high moldability are needed, consider E5008, E4008, E6008, etc., that use milled GF (crushed glass fiber).

(2) Glass fiber / inorganic reinforced grade

Grades where LCP is reinforced with glass fiber and inorganic filler have a combination of inorganic filler and glass fiber characteristics, and show high dimensional stability, low warpage, and high flowability while maintaining mechanical strength and heat resistance.

(3) Inorganic reinforced grade

The inorganic reinforced grade generally has better surface properties, higher tensile elongation, and better impact strength compared to the glass fiber reinforced grade. It also has high flowability.
