can be seen at 20% of glass fiber dry mix with the base material LLDPE. This type is
similar work that is found to be in agreement with past literature where Meireles et al.
checked the compatibility of waste materials with polystyrene (PS). They observed
the inexistency of CH 2 vibrating bond beyond 30% PS which suggested to utilize
the blend below 30% PS miscible with the waste materials [29].
Hence, the optimal blend can be recognized where both the peaks of LLDPE and
glass fiber is dominant, so that it can reflect the properties and characteristic of both
the material. Experiments showed the graphs of spectra which clearly revealed that
the dominance of peaks of both the powders is highly reflected at a mixture of 20%
of glass fiber blended with LLDPE.
