Summary: The research investigates the possibility of using particleboard made from coconut leaf sheath as raw material and low-density polyethylene as a binder. The study aims to improve particleboard's physical and mechanical characteristics by utilizing a twin-screw extruder, a two-roll mill, and a compression machine. Five mixed designs were produced. The following ratios are 10:90, 15:85, 20:80, 25:75, and 30:70 for the coconut leaf sheath (CLS) to low-density polyethylene (LDPE) binder. The particleboard's microstructure and physical and mechanical characteristics were all determined for the five mix designs. The results show that for the Physical Properties Test, all the samples have passed and met the requirements of each standard for thickness swelling and density variation. However, for the mechanical properties test, all the samples did not meet the standard for the modulus of rupture. However, the mix 5 (30:70) shows a significant result of 10.31 MPa, which almost passed the standard requirement of at least 10.50 MPa. Moreover, all the mixed ratios passed the requirements for the Internal Bond Test. The Philippine National Standard (PNS) used in this study is PNS ISO: 16893 2017. The researchers concluded that the Mix 5 (30:70) is the best mix ratio based on the proposed mix design. The combination of the coconut leaf sheath and low-density polyethylene proved that it is effective with the help of the twin-screw extruder, two-roll mill, and compression machine. The particleboard that was produced in this study can be used for aesthetic purposes such as ceiling and wall cladding.

The research investigates the possibility of using particleboard made from coconut leaf
sheath as raw material and low-density polyethylene as a binder. The study aims to improve
particleboard's physical and mechanical characteristics by utilizing a twin-screw extruder,
a two-roll mill, and a compression machine. Five mixed designs were produced. The
following ratios are 10:90, 15:85, 20:80, 25:75, and 30:70 for the coconut leaf sheath (CLS)
to low-density polyethylene (LDPE) binder. The particleboard's microstructure and
physical and mechanical characteristics were all determined for the five mix designs. The
results show that for the Physical Properties Test, all the samples have passed and met the
requirements of each standard for thickness swelling and density variation. However, for
the mechanical properties test, all the samples did not meet the standard for the modulus
of rupture. However, the mix 5 (30:70) shows a significant result of 10.31 MPa, which
almost passed the standard requirement of at least 10.50 MPa. Moreover, all the mixed
ratios passed the requirements for the Internal Bond Test. The Philippine National Standard
(PNS) used in this study is PNS ISO: 16893 2017. The researchers concluded that the Mix
5 (30:70) is the best mix ratio based on the proposed mix design. The combination of the
coconut leaf sheath and low-density polyethylene proved that it is effective with the help
of the twin-screw extruder, two-roll mill, and compression machine. The particleboard that
