Abstract

A composite made from the flexsible plastic waste and saw dust was studied. The objectives of this research was to find the optimum ratio of the flexible plastic waste and saw dust in its application on a floor tile. The investigated ratio of flexible plastic waste / saw dust were 100/0; 90/10; 80/20; 70/30; 60/40; and 50/50 respectively. The composites were prepared on a rheocord-90 machine at 600C for 10 minutes. The composites were tested for their physical properties I, e flexibility, dimensional stability, curling, volatility, tensile strength, elongation at break, and hardness. The physical properties testing result show that a composite by using the flexible plastic waste and saw dust in comparation of 90/10 could meet the requirements of SNI 03/4060/1996 for Vinyl Floor. The increasing saw dust content in composites decreased tensile strength, elongation at break, flexibility, and hardness, but increased dimensional stability, and volatility. Tensile strength of all composites was higher than particle board.   Keywords : composites, flexible plastic waste, saw dust, floor tile.

Abstract

Appied research rubber sole for canvas shoes sport of industry have observed of properties abrasion resistance and hardness with perform research on the process to shape sole in industry with variation time of 4, 5, 6, 7, 8 minutes and pressure of 145, 150, 155 kg/cm2 on temperature 150’C on the result 15 variation soles, until of result properties abrasion resistance = 0.1410 mm3/kgm and hardness = 70 shore A to shape with variation pressure 150 kg/cm2, time 6 minute and temperature 150’C ti fill means SNI 0171-1987 A : Canvas Shoes with Rubber Sole for Sport. INTISARI Penelitian penerapan sol karet sepatu kanvas untuk olah raga pada industry ditinjau dari sifat ketahanan kikis dan kekerasan dilakukan penelitian dengan proses pencetakan sol di industry dengan variasi waktu pencetakan sol 4, 5, 6, 7, 8 menit dan tekanan 145, 150, 155 kg/cm pada suhu 150’C diperoleh 15 variasi sol cetak, sehingga dari hasil penelitian diperoleh sifat ketahanan kikis = 0.1410 mm3/kgm dan kekerasan = 70 shore A dicetak dengan variasi tekanan 150 kg/cm, waktu 6 menit dan suhu 150’C memenuhi persyaratan SNI 0171-1987 A : Sepatu Kanvas dengan Sol Karet untuk Olah Raga.
