Latest Patents

Among his notable inventions, Okada has patented an **Automobile bumper formed of thermoplastic multicomponent resin**. This innovative bumper design enhances weatherability and impact resistance at low temperatures while improving surface glossiness. The resin composition comprises a blend of 22-28 wt % of a hydrogenated block copolymer of an aromatic vinyl compound such as styrene and a conjugated diene such as butadiene, alongside 32-56 wt % of a propylene-ethylene block copolymer and 22-28 wt % of an ethylene-propylene copolymer rubber. Additional options include 5 wt % of talc and/or 7 wt % of low-pressure low-density polyethylene. The physical properties are engineered to achieve a melt index not lower than 5 g/10 min at 230 degrees Celsius under a load of 2.16 kg, with a modulus of elasticity in bending between 2000 to 4000 kg/cm².

Another significant patent is the **Reinforcing adhesive sheet**, which incorporates a thermosetting reinforcing resin sheet containing a reinforcing material in an unhardened or semi-hardened state. This innovation features a bead-forming material that is narrower than the resin sheet and creates a bead-like projection before hardening. The bead-forming material consists of a flattened elastic foamed body containing a holding agent, allowing for recovery of its original form upon heating.
