LCA Study

Here are some examples of LCA studies of applications in which our phenolic molding compounds are used.
These are LCA examples of brake pistons and pulleys for automobiles made of phenolic molding compounds.
We use MiLCA, a globally recognized LCA calculation module for calculation. Please contact us for more information.

CO2 Emissions of Composite Automotive Parts

Phenolic Brake Pistons

LCA Study: Phenolic Brake Pistons
CO2 emissions per 1 kg of product
(kg-CO2e/kg)		 CO2 emissions per 1 product (0.2 kg)
(kg-CO2e/kg)
Molding Material
(Molding Material and its Raw Material)		 1.62 0.32
Parts Manufacturing
(Molding process)		 0.24 0.05
Sum 1.86 0.37
Disposal
(incineration, recycling, etc.)		 Our Environmentally Friendly Technology Brings Them Closer To Zero.

CO2 emissions related to parts production amount to 0.925 kg-CO2eq per vehicle*.
(* Estimated at an average of 2.5 pc/vehicle)
Phenolic compounds are expected to reduce CO2 emissions
due to the difference in production methods from conventional materials.

Transition of Phenolic Molding Materials and Our Environmental Initiatives (1950-2023)

Features

Non-ammonia material

Our high reliable non-ammonia grade has extremely low metal corrosion and excellent electrical properties.

Excellent solder heat resistance

High heat resistance over 400°C meets high cycle requirement in solder reflow process of SMT.

Non-halogen flame retardant materials

Many kinds of thermoplastics lose their mechanical strength to get non-halogen flame retardancy. Our non-halogen flame retardant phenolic molding compounds for transformer bobbin has high mechanical strength with cost-effectiveness.
Major grades are approved for UL1446 insulation system (Class B).

Tracking resistance (CTI:250V) compliant

Good balance of CTI (comparative tracking index) and mechanical strength for high frequency and high voltage requirement in electrical components.

Commutator materials

Excellent mechanical strength, heat resistance, humidity resistance and dimensional stability improve revolution at burst and bar-to-bar movement for noise reduction and brush wear. Processability such as slitting, press-fitting of shaft and fusing is also excellent.

High reliability

Outperform engineering thermoplastic with high heat resistance, rigidity at high temperature and good creep property at high temperature.

Good dimensional stability

Good transcription ability to cavity and good dimensional stability.

Wide range of design flexibility

Good moldability for wide range of thickness from thin parts (100microns) to thick parts (tens of mm), complicated shape or uneven thickness parts.

Environmental compatibility

Environmental loading
material free		 ： Asbestos free, halogen free
Recycle ： Thermal recycle
Material recycle
※ We develop the world's first Chemical Recycle Technology for Phenolics.
