Selection of colors:
High molecular polymer / Polyether polyol fire retardant acoustic foam.
E0 Eco-friendly water based paint.
High-density Polyether polyol acoustic foam improves the sound that the model absorbs; QRD array achieves broadband frequency absorption, solving the problem arise from too much high frequency and balanced reflection.
Zero Formaldehyde emission; E0 standard
