Applications:
The main difference of hydrocarbon resin “Ekokanplast” from other hydrocarbon resins is its reduced content of PAHs (mass concentration of naphthalene no more than 10 mg/kg, sum of 18 PAHs — no more than 50 mg/kg). It is used as a plasticizer for rubber compounds, a component of adhesive compositions, paint materials, and composite mixtures for the production of targets for shooting sports, as well as a synthetic substitute for pine and tall oil rosin.
