yung Acoustic Pad na brand na gamit nya nakalagay sa sulit Asphalt daw ito. Baka mayroon pa siyang other brand na hindi asphalt.


nakalagay sa sulit from tedtamayo

* Odorless kasi asphalt made at dumaan sa tamang process, di tulad ng butyl deadening na purely made of rubber mabaho pag nainitan,,,,,

tama ba nakaadvertise?

Nah. Wrong advertising

based on post of jhnkvn mas better ang asphalt than butyl. kaya butyl na kinuha ko para in the long run wala ng sakit ng ulo na babaklasin at lalagyan ulit.

my next project is HU.

It's the opposite. I prefer butyl over asphalt.

For those who want additional information on deadening. Butyl doesn't guarantee you a more effective damper.. but it does guarantee you peace of mind at the expense of additional cost.

Many deadening manufacturers still use asphalt. This is because, kahit ano gawin mo, many buyers are conscious of cost and less on the quality especially when most of them are uninformed ("deadening is deadening"). For one, the original Dynamat (arguably the most famous deadener brand out there) used asphalt before they introduced the Dynamat Extreme which is made of butyl and aluminum (like StandartPlast/StP). I believe they have since discontinued the use of asphalt-based Dynamats.

The main argument of going for butyl is that asphalt has a low melting point compared to butyl. Even the lowest-grade butyl can withstand temperatures more than 100C. On the other hand, asphalt generally starts melting from 90-100C. Now, this is a high temperature to reach but it's possible in our climate because this is metal we're talking about -- it absorbs heat like crap.

It's not really uncommon to hear some horror stories regarding asphalt deadeners. If exposed to heat, it'll turn gooey.. like this photo:



And trust me, removing that goo is a literal pain in the ass if you will have your panel removed. The lower-grade asphalt emits a smell.. but higher-grade asphalt are more or less unoffensive when melted.
